PPC: Add CPU local MMIO regions to MPIC

The MPIC exports a register set for each CPU connected to it. They can all
be accessed through specific registers or using a shadow page that is mapped
differently depending on which CPU accesses it.

This patch implements the shadow map, making it possible for guests to access
the CPU local registers using the same address on each CPU.
