powerpc/fsl-booke: Use HW PTE format if CONFIG_PTE_64BIT
Switch to using the Power ISA defined PTE format when we have a 64-bit PTE. This makes the code handling between fsl-booke and book3e-64 similiar for TLB faults. Additionally this lets use take advantage of the page size encodings and full permissions that the HW PTE defines. Also defined _PMD_PRESENT, _PMD_PRESENT_MASK, and _PMD_BAD since the 32-bit ppc arch code expects them.
