[POWERPC] Split out asm-ppc/mmu.h portions for Freescale Book-E

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 Freescale Book-E which are still relevant
in arch/powerpc and puts them in a new asm-powerpc/mmu-fsl-booke.h,
included when appropriate from asm-powerpc/mmu.h.
