From: Jonah Palmer <jonah.palmer@oracle.com>

Add support for the VIRTIO_F_NOTIFICATION_DATA feature across a variety
of vhost devices.

The inclusion of VIRTIO_F_NOTIFICATION_DATA in the feature bits arrays
for these devices ensures that the backend is capable of offering and
providing support for this feature, and that it can be disabled if the
backend does not support it.
