[PATCH] ppc32: make usage of CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT consistent
CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT are not currently consistently used in
the code base. Fixed up the usage such that CONFIG_PTE_64BIT is used when we
have a 64-bit PTE regardless of physical address width. CONFIG_PHYS_64BIT is
used if the physical address width is larger than 32-bits, regardless of PTE
size.
These changes required a few sub-arch specific ifdef's to be fixed and the
introduction of a physical address format string.
