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.).
