powerpc: Add memory management headers for new 64-bit BookE
This adds the PTE and pgtable format definitions, along with changes to the kernel memory map and other definitions related to implementing support for 64-bit Book3E. This also shields some asm-offset bits that are currently only relevant on 32-bit We also move the definition of the "linux" page size constants to the common mmu.h file and add a few sizes that are relevant to embedded processors.
