drm/vboxvideo: Switch to drm_atomic_helper_dirty_fb()
The vboxvideo driver provides struct drm_framebuffer_funcs.dirty_fb from
its own implementation. Switch over to drm_atomic_helper_dirty_fb() and
handle screen updates in the primary plane's atomic_update function.
With dirty_fb out of the way, we can further replace struct vbox_frammebuffer
with generic code.
