This patch makes a start to sorting out the tangled mess of MMU
related header files in asm-powerpc, and weaning arch/powerpc off the
remaining asm-ppc headers it uses.

Specifically it splits the ppc64 specific (or more strictly, the
64-bit hash table specific) parts of asm-powerpc/mmu.h into its own
file, asm-powerpc/mmu-hash64/mmu.h.  Similarly, PowerPC 44x
definitions are taken from asm-ppc/mmu.h, trimmed down for use in
arch/powerpc and place in their own file, asm-powerpc/mmu-44x/mmu.h.

mmu.h definitions for other 32-bit MMU types remain in asm-ppc/mmu.h
for now, but should be likewise split into their own files.

I asked this before, but why the need for a separate directory per  
mmu type?  why not just include/asm-powerpc/mmu-44x.h?

Because I have further patches in the works that add MMU specific
versions of tlbflush.h, pgtable.h and so forth to the same
directories.

I'm not wedded to the idea, but it seemed like a reasonable way to
organize things.
