Initial skeleton for libkvm powerpc support

This patch is to add initial skelton code for powerpc.
No big implimentations as kernel code is still being worked out.
But it can be a good template for other architectures. Once kernel
code makes it upstream (and is for the most part finalized) then
implimentaions will follow.
