KVM: PPC: Implement kvmppc_xlate for all targets
We have a nice API to find the translated GPAs of a GVA including protection
flags. So far we only use it on Book3S, but there's no reason the same shouldn't
be used on BookE as well.
Implement a kvmppc_xlate() version for BookE and clean it up to make it more
readable in general.
