drm/virtio: Enable fb damage clips property for the primary plane 



Christian Hergert reports that the driver doesn't enable the property and
that leads to always doing a full plane update, even when the driver does
support damage clipping for the primary plane.

Don't enable it for the cursor plane, because its .atomic_update callback
doesn't handle damage clips.
