Now that we've implemented -cpu host for ppc, this patch updates the pseries machine to use the host cpu as the guest cpu by default when running under KVM. This is important because under KVM Book3S-HV the guest cpu _cannot_ be of a different type to the host cpu (at the moment KVM Book3S-HV will silently virtualize the host cpu instead of whatever was requested, but in future it is likely to simply refuse to run the VM if a cpu model other than the host's is requested).
