The e6500 core used on T4240 and B4860 SoCs from FSL implements MMUv2 of
the Power Book-E Architecture.  However there are some minor differences
between it and other Book-E implementations.

Add support to parse SPRN_TLB1PS for the variable page sizes supported.

e6500 as well as other MMU features.

The T4240 utilizes a new PCIe controller block that has some minor
programming model differences from previous versions.

The major one that impacts initialization is how we determine the link
state.  On the 3.x controllers we have a memory mapped SoC register
instead of a PCI config register that reports the link state.

Currently we use the link register to branch up high in the early MMU on
syscall entry path.  Unfortunately, this trashes the link stack as the
address we are going to is not associated with the earlier mflr.

This patch simply converts us to used the count register (volatile over
syscalls anyway) instead.  This is much better at predicting in this
scenario and doesn't trash link stack causing a bunch of additional
branch mispredicts later.  Benchmarking this on POWER8 saves a bunch of
cycles on Anton's null syscall benchmark here:
