Commit dc5698e80cf7 ("Add virtio gpu driver.") declared but never
implemented virtio_gpu_attach_status_page()/virtio_gpu_detach_status_page()
Also commit 62fb7a5e1096 ("virtio-gpu: add 3d/virgl support")
declared but never implemented virtio_gpu_fence_ack() and
virtio_gpu_dequeue_fence_func().
Commit c84adb304c10 ("drm/virtio: Support virtgpu exported resources")
