powerpc/85xx: Add support for Book-E MMU Arch v2.0

A few of the config registers changed definition between MMU v1.0 and
MMUv2.0.  The new e6500 core from Freescale implements v2.0 of the
architecture.

Specifically, how we determine the size of TLB entries we support in the
variable size (or TLBCAM/TLB1) array is specified in a new register
(TLBnPS - TLB n Page size) instead of via TLBnCFG.
