from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

Moved phys_addr_t out of mmu-*.h and into asm/types.h so we can use it in
places that before would have caused recursive includes.

For example to use phys_addr_t in <asm/page.h> we would have included
<asm/mmu.h> which would have possibly included <asm/mmu-hash64.h> which
includes <asm/page.h>.  Wheeee recursive include.

CONFIG_PHYS_64BIT is a bit counterintuitive in light of ppc64 systems
and thus the config option is only used for ppc32 systems with >32-bit
physical addresses (44x, 85xx, 745x, etc.).

arch/powerpc still relies on asm-ppc/mmu.h for some 32-bit MMU types.
This patch is another step towards fixing this.  It takes the portions
of asm-ppc/mmu.h related to 8xx embedded CPUs which are still relevant
in arch/powerpc and puts them in a new asm-powerpc/mmu-8xx.h,
included when appropriate from asm-powerpc/mmu.h.
