wanrouter: delete now orphaned header content, files/drivers

The wanrouter support was identified earlier as unused for years,
and so the previous commit totally decoupled it from the kernel,
leaving the related wanrouter files present, but totally inert.

Here we take the final step in that cleanup, by doing a wholesale
removal of these files.  The two step process is used so that the
large deletion is decoupled from the git history of files that we
still care about.

The drivers deleted here all were dependent on the Kconfig setting
CONFIG_WAN_ROUTER_DRIVERS.

A stub wanrouter.h header (kernel & uapi) are left behind so that
drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that
we don't accidentally break userspace that expected these defines.

-* ============================================================================
-* 1999/11/11	acme		set_current_state(TASK_INTERRUPTIBLE), code
-*				cleanup
-* 1999/11/08	acme		init_cyc2x deleted, doing nothing
-* 1999/11/06	acme		back to read[bw], write[bw] and memcpy_to and
-*				fromio to use dpmbase ioremaped
-* 1999/10/26	acme		use isa_read[bw], isa_write[bw] & isa_memcpy_to
-*				& fromio
-* 1999/10/23	acme		cleanup to only supports cyclom2x: all the other
-*				boards are no longer manufactured by cyclades,
-*				if someone wants to support them... be my guest!
-* 1999/05/28    acme		cycx_intack & cycx_intde gone for good
-* 1999/05/18	acme		lots of unlogged work, submitting to Linus...
-* 1999/01/03	acme		more judicious use of data types
-* 1999/01/03	acme		judicious use of data types :>
-*				cycx_inten trying to reset pending interrupts
-*				from cyclom 2x - I think this isn't the way to
-*				go, but for now...
-* 1999/01/02	acme		cycx_intack ok, I think there's nothing to do
-*				to ack an int in cycx_drv.c, only handle it in
-*				cyx_isr (or in the other protocols: cyp_isr,
-*				cyf_isr, when they get implemented.
-* Dec 31, 1998	acme		cycx_data_boot & cycx_code_boot fixed, crossing
-*				fingers to see x25_configure in cycx_x25.c
-*				work... :)
-* Dec 26, 1998	acme		load implementation fixed, seems to work! :)
-*				cycx_2x_dpmbase_options with all the possible
-*				DPM addresses (20).
-*				cycx_intr implemented (test this!)
-*				general code cleanup
-* Dec  8, 1998	Ivan Passos	Cyclom-2X firmware load implementation.
-* Aug  8, 1998	acme		Initial version.

-*				called to iounmap the dpmbase)
-* 1999/08/09	acme		removed references to enable_tx_int
-*				use spinlocks instead of cli/sti in
-*				cyclomx_set_state
-* 1999/05/19	acme		works directly linked into the kernel
-*				init_waitqueue_head for 2.3.* kernel
-* 1999/05/18	acme		major cleanup (polling not needed), etc
-* 1998/08/28	acme		minor cleanup (ioctls for firmware deleted)

-* ============================================================================
-* 2001/01/12	acme		use dev_kfree_skb_irq on interrupt context
-* 2000/04/02	acme		dprintk, cycx_debug
-* 				fixed the bug introduced in get_dev_by_lcn and
-* 				get_dev_by_dte_addr by the anonymous hacker
-* 				that converted this driver to softnet
-* 2000/01/08	acme		cleanup
-* 1999/10/27	acme		use ARPHRD_HWX25 so that the X.25 stack know
-*				that we have a X.25 stack implemented in
-*				firmware onboard
-* 1999/10/18	acme		support for X.25 sockets in if_send,
-*				beware: socket(AF_X25...) IS WORK IN PROGRESS,
-*				TCP/IP over X.25 via wanrouter not affected,
-*				working.
-* 1999/10/09	acme		chan_disc renamed to chan_disconnect,
-* 				began adding support for X.25 sockets:
-* 				conf->protocol in new_if
-* 1999/10/05	acme		fixed return E... to return -E...
-* 1999/08/10	acme		serialized access to the card thru a spinlock
-*				in x25_exec
-* 1999/08/09	acme		removed per channel spinlocks
-*				removed references to enable_tx_int
-* 1999/05/28	acme		fixed nibble_to_byte, ackvc now properly treated
-*				if_send simplified
-* 1999/05/25	acme		fixed t1, t2, t21 & t23 configuration
-*				use spinlocks instead of cli/sti in some points
-* 1999/05/24	acme		finished the x25_get_stat function
-* 1999/05/23	acme		dev->type = ARPHRD_X25 (tcpdump only works,
-*				AFAIT, with ARPHRD_ETHER). This seems to be
-*				needed to use socket(AF_X25)...
-*				Now the config file must specify a peer media
-*				address for svc channels over a crossover cable.
-*				Removed hold_timeout from x25_channel_t,
-*				not used.
-*				A little enhancement in the DEBUG processing
-* 1999/05/22	acme		go to DISCONNECTED in disconnect_confirm_intr,
-*				instead of chan_disc.
-* 1999/05/16	marcelo		fixed timer initialization in SVCs
-* 1999/01/05	acme		x25_configure now get (most of) all
-*				parameters...
-* 1999/01/05	acme		pktlen now (correctly) uses log2 (value
-*				configured)
-* 1999/01/03	acme		judicious use of data types (u8, u16, u32, etc)
-* 1999/01/03	acme		cyx_isr: reset dpmbase to acknowledge
-*				indication (interrupt from cyclom 2x)
-* 1999/01/02	acme		cyx_isr: first hackings...
-* 1999/01/0203  acme 		when initializing an array don't give less
-*				elements than declared...
-* 				example: char send_cmd[6] = "?\xFF\x10";
-*          			you'll gonna lose a couple hours, 'cause your
-*				brain won't admit that there's an error in the
-*				above declaration...  the side effect is that
-*				memset is put into the unresolved symbols
-*				instead of using the inline memset functions...
-* 1999/01/02    acme 		began chan_connect, chan_send, x25_send
-* 1998/12/31	acme		x25_configure
-*				this code can be compiled as non module
-* 1998/12/27	acme		code cleanup
-*				IPX code wiped out! let's decrease code
-*				complexity for now, remember: I'm learning! :)
-*                               bps_to_speed_code OK
-* 1998/12/26	acme		Minimal debug code cleanup
-* 1998/08/08	acme		Initial version.
