[POWERPC] Start factoring pgtable-ppc32.h and pgtable-ppc64.h
This factors some things defined in both pgtable-ppc32.h and pgtable-ppc64.h into the common part of asm-powerpc/pgtable.h. These are all things which have essentially identical definitions, and which by their nature are very unlikely ever to need different definitions in the two cases.
