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

Move virtio_gpu_notify() to higher-level functions for virtio_gpu_cmd_resource_flush(), virtio_gpu_cmd_set_scanout() and virtio_gpu_cmd_transfer_to_host_{2d,3d}(). virtio_gpu_primary_plane_update() will notify only once for a series of commands (restores plane update command batching).
