[PATCH v2 0/9] Stateless H.264 de-staging

[Ezequiel Garcia]

Now that H.264 stateless controls are solid, we can get it
out of staging.

Following some guidelines from Hans, this series creates a
new stateless control class for the stable codec controls to land.

While here, I'm including a patch from Jonas adding profiles
and levels to Rkvdec, and also made a similar fix for Cedrus.

This series was tested on a i.MX8MQ EVK board, using GStreamer:

https://gitlab.freedesktop.org/ezequielgarcia/gst-plugins-bad/-/commits/h264_stable_uapi

In case someone wants to give this a test.

Note that v4l2-compliance isn't passing, as the Hantro driver
doesn't set legal default values for the H264 SPS, PPS, etc
controls.

That's something we should fix, although it's since it's just
meant to please v4l2-compliance, we could also argue that these
controls shouldn't be expected to have any default value.

Thanks,
Ezequiel

v2:
  * Split destage changes in several patches so it's easier to review.
  * Added missing changes to drivers/media/v4l2-core/v4l2-ctrls.c.
  * Renamed V4L2_CID_CODEC_CX2341X_ and V4L2_CID_MPEG_MFC51_
  * Moved the compatibility macros for MPEG to the end of the header.
