drm/virtio: batch display update commands.
When the driver submits multiple commands in a row it makes sense to
notify the host only after submitting the last one, so the host can
process them all at once, with a single vmexit.
Add functions to enable/disable notifications to allow that. Use the
new functions for primary plane updates.
