Given the stateful codec specification is still a moving target,
it doesn't make any sense to try to comply fully with it.

On the other side, we can still comply with some basic userspace
expectations, with just a couple small changes.

This series implements proper resolution changes propagation,
and fixes the CMD_STOP so it actually works.

The intention of this series is to be able to test this driver
using already existing userspace, gstreamer in particular.
With this changes, it's possible to construct variations of
this pipeline:

  gst-launch-1.0 videotestsrc ! v4l2fwhtenc ! v4l2fwhtdec ! fakevideosink
