pnv: Add cpu unrealize path 

Currently we don't have any unrealize path for pnv cpu cores.  We get away
with this because we don't yet support cpu hotplug for pnv.

However, we're going to want it eventually, and in the meantime, it makes
it non-obvious why there are a bunch of allocations on the realize() path
that don't have matching frees.

So, implement the missing unrealize path.
