s390x/cpumodel: allow zpci features in qemu model
AEN and AIS can be provided unconditionally, ZPCI should be turned on manually. With -cpu qemu,zpci=on, the guest kernel can now successfully detect virtio-pci devices under tcg. Also fixup the order of the MSA_EXT_{3,4} flags while at it. Reviewed-by: David Hildenbrand <david@redhat.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com>
