[libvirt] [PATCH v2 23/25] qemu: Support virtio-serial controller model=virtio-{non-}transitional



Add controller type='virtio-serial' model handling for virtio
transitional devices. Ex:

  <controller type='virtio-serial' model='virtio-transitional'/>

* "virtio-transitional" maps to qemu "virtio-serial-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-serial-pci-non-transitional"
