KVM: PPC: Use HIOR setting for -M pseries with PR KVM

Browse Source 
When running with PR KVM, we need to set HIOR directly. Thankfully there
is now a new interface to set registers individually so we can just use that
and poke HIOR into the guest vcpu's HIOR register.

While at it, this also sets SDR1 because -M pseries requires it to run.

With this patch, -M pseries works properly with PR KVM.
