Having it here rather than in arch/ppc64/kernel/smp.c means that
we can use it on 32-bit SMP systems easily with ARCH=powerpc.

Complete moving arch/ppc64/kernel/mpic.h,
include/asm-ppc/reg.h, include/asm-ppc64/kdebug.h
and include/asm-ppc64/kprobes.h
Add arch/powerpc/platforms/Makefile and use it from
arch/powerpc/Makefile
Introduce OLDARCH temporarily so we can point back to
the originating architecture

This creates the directory structure under arch/powerpc and a bunch
of Kconfig files. It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.
For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes
to files in those directories and files outside arch/powerpc.
The boot directory is still not merged. That's going to be interesting.
