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.
