fbdev/intelfb: Remove driver

From looking at the PCI IDs, every device supported by intelfb is
also supported by i915. Anyone still using intelfb should please
move on to i915, which does everything intelfb does but better.

Removing intelfb is motivated by the driver's excessive use of the
global screen_info state. The state belongs to architecture and
firmware code; device drivers should not attempt to access it. But
fixing intelfb would require a significant change in the driver's
probing logic. As intelfb has been obsolete for nearly 2 decades,
it is probably not worth the effort. Let's just remove it. Also
remove the related documentation.

-=============================================================
-Intel 830M/845G/852GM/855GM/865G/915G/945G Framebuffer driver
-=============================================================
-
-A. Introduction
-===============
-
-This is a framebuffer driver for various Intel 8xx/9xx compatible
-graphics devices.  These would include:
-
-	- Intel 830M
-	- Intel 845G
-	- Intel 852GM
-	- Intel 855GM
-	- Intel 865G
-	- Intel 915G
-	- Intel 915GM
-	- Intel 945G
-	- Intel 945GM
-	- Intel 945GME
-	- Intel 965G
-	- Intel 965GM
-
-B.  List of available options
-=============================
-
-   a. "video=intelfb"
-	enables the intelfb driver
-
-	Recommendation: required
-
-   b. "mode=<xres>x<yres>[-<bpp>][@<refresh>]"
-	select mode
-
-	Recommendation: user preference
-	(default = 1024x768-32@70)
-
-   c. "vram=<value>"
-	select amount of system RAM in MB to allocate for the video memory
-	if not enough RAM was already allocated by the BIOS.
-
-	Recommendation: 1 - 4 MB.
-	(default = 4 MB)
-
-   d. "voffset=<value>"
-	select at what offset in MB of the logical memory to allocate the
-	framebuffer memory.  The intent is to avoid the memory blocks
-	used by standard graphics applications (XFree86). Depending on your
-	usage, adjust the value up or down, (0 for maximum usage, 63/127 MB
-	for the least amount).  Note, an arbitrary setting may conflict
-	with XFree86.
-
-	Recommendation: do not set
-	(default = 48 MB)
-
-   e. "accel"
-	enable text acceleration.  This can be enabled/reenabled anytime
-	by using 'fbset -accel true/false'.
-
-	Recommendation: enable
-	(default = set)
-
-   f. "hwcursor"
-	enable cursor acceleration.
-
-	Recommendation: enable
-	(default = set)
-
-   g. "mtrr"
-	enable MTRR.  This allows data transfers to the framebuffer memory
-	to occur in bursts which can significantly increase performance.
-	Not very helpful with the intel chips because of 'shared memory'.
-
-	Recommendation: set
-	(default = set)
-
-   h. "fixed"
-	disable mode switching.
-
-	Recommendation: do not set
-	(default = not set)
-
-   The binary parameters can be unset with a "no" prefix, example "noaccel".
-   The default parameter (not named) is the mode.
-
-C. Kernel booting
-=================
-
-Separate each option/option-pair by commas (,) and the option from its value
-with an equals sign (=) as in the following::
-
-	video=intelfb:option1,option2=value2
-
-Sample Usage
-------------
-
-In /etc/lilo.conf, add the line::
-
-	append="video=intelfb:mode=800x600-32@75,accel,hwcursor,vram=8"
-
-This will initialize the framebuffer to 800x600 at 32bpp and 75Hz. The
-framebuffer will use 8 MB of System RAM. hw acceleration of text and cursor
-will be enabled.
-
-Remarks
--------
-
-If setting this parameter doesn't work (you stay in a 80x25 text-mode),
-you might need to set the "vga=<mode>" parameter too - see vesafb.txt
-in this directory.
-
-
-D.  Module options
-==================
-
-The module parameters are essentially similar to the kernel
-parameters. The main difference is that you need to include a Boolean value
-(1 for TRUE, and 0 for FALSE) for those options which don't need a value.
-
-Example, to enable MTRR, include "mtrr=1".
-
-Sample Usage
-------------
-
-Using the same setup as described above, load the module like this::
-
-	modprobe intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
-
-Or just add the following to a configuration file in /etc/modprobe.d/::
-
-	options intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
-
-and just do a::
-
-	modprobe intelfb
-
-
-E.  Acknowledgment:
-===================
-
-	1.  Geert Uytterhoeven - his excellent howto and the virtual
-	    framebuffer driver code made this possible.
-
-	2.  Jeff Hartmann for his agpgart code.
-
-	3.  David Dawes for his original kernel 2.4 code.
-
-	4.  The X developers.  Insights were provided just by reading the
-	    XFree86 source code.
-
-	5.  Antonino A. Daplas for his inspiring i810fb driver.

- * Changes:
- *    01/2003 - Initial driver (0.1.0), no mode switching, no acceleration.
- *		This initial version is a basic core that works a lot like
- *		the vesafb driver.  It must be built-in to the kernel,
- *		and the initial video mode must be set with vga=XXX at
- *		boot time.  (David Dawes)
- *
- *    01/2003 - Version 0.2.0: Mode switching added, colormap support
- *		implemented, Y panning, and soft screen blanking implemented.
- *		No acceleration yet.  (David Dawes)
- *
- *    01/2003 - Version 0.3.0: fbcon acceleration support added.  Module
- *		option handling added.  (David Dawes)
- *
- *    01/2003 - Version 0.4.0: fbcon HW cursor support added.  (David Dawes)
- *
- *    01/2003 - Version 0.4.1: Add auto-generation of built-in modes.
- *		(David Dawes)
- *
- *    02/2003 - Version 0.4.2: Add check for active non-CRT devices, and
- *		mode validation checks.  (David Dawes)
- *
- *    02/2003 - Version 0.4.3: Check when the VC is in graphics mode so that
- *		acceleration is disabled while an XFree86 server is running.
- *		(David Dawes)
- *
- *    02/2003 - Version 0.4.4: Monitor DPMS support.  (David Dawes)
- *
- *    02/2003 - Version 0.4.5: Basic XFree86 + fbdev working.  (David Dawes)
- *
- *    02/2003 - Version 0.5.0: Modify to work with the 2.5.32 kernel as well
- *		as 2.4.x kernels.  (David Dawes)
- *
- *    02/2003 - Version 0.6.0: Split out HW-specifics into a separate file.
- *		(David Dawes)
- *
- *    02/2003 - Version 0.7.0: Test on 852GM/855GM.  Acceleration and HW
- *		cursor are disabled on this platform.  (David Dawes)
- *
- *    02/2003 - Version 0.7.1: Test on 845G.  Acceleration is disabled
- *		on this platform.  (David Dawes)
- *
- *    02/2003 - Version 0.7.2: Test on 830M.  Acceleration and HW
- *		cursor are disabled on this platform.  (David Dawes)
- *
- *    02/2003 - Version 0.7.3: Fix 8-bit modes for mobile platforms
- *		(David Dawes)
- *
- *    02/2003 - Version 0.7.4: Add checks for FB and FBCON_HAS_CFB* configured
- *		in the kernel, and add mode bpp verification and default
- *		bpp selection based on which FBCON_HAS_CFB* are configured.
- *		(David Dawes)
- *
- *    02/2003 - Version 0.7.5: Add basic package/install scripts based on the
- *		DRI packaging scripts.  (David Dawes)
- *
- *    04/2003 - Version 0.7.6: Fix typo that affects builds with SMP-enabled
- *		kernels.  (David Dawes, reported by Anupam).
- *
- *    06/2003 - Version 0.7.7:
- *              Fix Makefile.kernel build problem (Tsutomu Yasuda).
- *		Fix mis-placed #endif (2.4.21 kernel).
- *
- *    09/2004 - Version 0.9.0 - by Sylvain Meyer
- *              Port to linux 2.6 kernel fbdev
- *              Fix HW accel and HW cursor on i845G
- *              Use of agpgart for fb memory reservation
- *              Add mtrr support
- *
- *    10/2004 - Version 0.9.1
- *              Use module_param instead of old MODULE_PARM
- *              Some cleanup
- *
- *    11/2004 - Version 0.9.2
- *              Add vram option to reserve more memory than stolen by BIOS
- *              Fix intelfbhw_pan_display typo
- *              Add __initdata annotations
- *
- *    04/2008 - Version 0.9.5
- *              Add support for 965G/965GM. (Maik Broemme <mbroemme@plusserver.de>)
- *
- *    08/2008 - Version 0.9.6
- *              Add support for 945GME. (Phil Endecott <spam_from_intelfb@chezphil.org>)
