Add an option to force usage of the in-kernel cmdline even if the boot
loader passes another command string to the kernel.

Useful if someone cannot or don't want to change the
command-line options of the boot loader but is able to change
the kernel.

The 'outer_cache' variable is needed by the outer_inv_range(),
outer_clean_range() and outer_flush_range() functions, which are
declared as inline in asm/cacheflush.h.  Otherwise drivers built
as a loadable module, which access these functions, will have
an undefined symbol.

drivers/of/fdt expects a cmd_line symbol, while arm uses command_line.
Change to the former, so that we can eventually share with the fdt
code.

The ARM setup code includes its own parser for early params, there's
also one in the generic init code.

This patch removes __early_init (and related code) from
arch/arm/kernel/setup.c, and changes users to the generic early_init
macro instead.

The generic macro takes a char * argument, rather than char **, so we
need to update the parser functions a little.

This adds the TCM interface to Linux, when active, it will
detect and report TCM memories and sizes early in boot if
present, introduce generic TCM memory handling, provide a
generic TCM memory pool and select TCM memory for the U300
platform.

The cacheid_init() function assumes that if cpu_architecture() returns
7, the caches are VIPT_NONALIASING. The cpu_architecture() function
returns the version of the supported MMU features (e.g. TEX remapping)
but it doesn't make any assumptions about the cache type. The patch adds
the checking of the Cache Type Register for the ARMv7 format.
