The guest firmware provides the same functionality as the pvpanic device, which is not available in QEMU on pSeries: make sure the XML reflects this fact by automatically adding a <panic/> element when not already present.
On the other hand, unlike the pvpanic device, the guest firmware can't be configured, so report an error if an address has been provided in the XML.
