Gerd Hoffmann cca41da100 drm/virtio: rework notification for better batching 
Drop the virtio_gpu_{disable,enable}_notify().  Add a new
virtio_gpu_notify() call instead, which must be called whenever
the driver wants make sure the host is notified needed.

Drop automatic notification from command submission.  Add
virtio_gpu_notify() calls after each command query instead.
This allows more fine-grained control over host notification
and can move around the notify calls in subsequent patches to
batch command submissions. With this in place it is also
possible to make notification optional for userspace ioctls.

Page flip batching goes away (temporarely).

v3:
 - move batching to separate patches.
v2:
 - rebase to latest drm-misc-next.
 - use "if (!atomic_read())".
 - add review & test tags.
