rS295520: Migrate the PTE format for book-e to standardize on the 'indirect PTE' format
Summary

The revised Book-E spec, adding the specification for the MMUv2 and e6500,
includes a hardware PTE layout for indirect page tables. In order to support
this in the future, migrate the PTE format to match the MMUv2 hardware PTE
format.

Test Plan

Boot tested on a P5020 board. Booted to multiuser mode.

Don't use a bitfield for the PTE. Instead, use bitmasks, like the rest of
powerpc.
