KVM: PPC: Book3S HV P9: Reduce mtmsrd instructions required to save host SPRs
This reduces the number of mtmsrd required to enable facility bits when
saving/restoring registers, by having the KVM code set all bits up front
rather than using individual facility functions that set their particular
MSR bits.
