KVM: PPC: Ignore PIR writes
While technically it's legal to write to PIR and have the identifier changed, we don't implement logic to do so because we simply expose vcpu_id to the guest. So instead, let's ignore writes to PIR. This ensures that we don't inject faults into the guest for something the guest is allowed to do. While at it, we cross our fingers hoping that it also doesn't mind that we broke its PIR read values.
