drm/virtio: batch plane updates (pageflip)

Browse Source 
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).
