[ARM PATCH] 2431/1: Split arch specifics out of arch/arm/kernel/debug.S 

Patch from Ben Dooks

This patch moves all the machine/arch specific bits out of
arch/arm/kernel/debug.S and places them into the include
directories for those given architectures. The debug macros
are placed into include/asm-arm/arch-*/debug-macro.S.
The aim is to clean-up the debug.S code and make it easier to
modify a single-architecture without affecting the entire
debug.S file.
The patch also removes CONFIG_ARCH_FTVPCI, which no longer
exists anywhere else in the kernel.
All new include files have the original copyright notice
from arch/arm/kernel/debug.S.
Note, not all architectures modified here have been built
and/or tested due to lack of available machines, or
problems building for them (no defconfig available, or
problems with kernel build).
