d04ceb3fc2 [POWERPC] Move phys_addr_t definition into asm/types.h
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.).

8e561e7eda [POWERPC] Kill typedef-ed structs for hash PTEs and BATs
Using typedefs to rename structure types if frowned on by CodingStyle.
However, we do so for the hash PTE structure on both ppc32 (where it's
called "PTE") and ppc64 (where it's called "hpte_t").  On ppc32 we
also have such a typedef for the BATs ("BAT").

This removes this unhelpful use of typedefs, in the process
bringing ppc32 and ppc64 closer together, by using the name "struct
hash_pte" in both cases.

4db68bfe71 [POWERPC] Split out asm-ppc/mmu.h portions for the "classic" hash-based MMU
arch/powerpc still relies on asm-ppc/mmu.h for most 32-bit MMU types.
This is another step towards fixing this.  It takes the portions
of asm-ppc/mmu.h related to the "classic" 32-bit hash page table MMU
which are still relevant in arch/powerpc and puts them in a new
asm-powerpc/mmu-hash32.h, included when appropriate from
asm-powerpc/mmu.h.
