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.
