Add support to virtio-ccw devices for handling the extra data sent from
the driver to the device when the VIRTIO_F_NOTIFICATION_DATA transport
feature has been negotiated.
The extra data that's passed to the virtio-ccw device when this feature
is enabled varies depending on the device's virtqueue layout.
That data passed to the virtio-ccw device is in the same format as the
data passed to virtio-pci devices.
