Subject: [PATCH v3 00/15] media: mtk-vcodec: support for MT8183 decoder

Please ignore the v2 of this series since I neglected a final check on
it and realized later it did not compile. >_<

This series adds support for the stateless API into mtk-vcodec, by first
separating the stateful ops into their own source file, and introducing
a new set of ops suitable for stateless decoding. As such, support for
stateful decoders should remain completely unaffected.

This series has been tested with both MT8183 and MT8173. Decoding was
working for both chips, and in the case of MT8173 no regression has been
spotted.

Patches 1-9 add MT8183 support to the decoder using the stateless API.
MT8183 only support H.264 acceleration.

Patches 10-15 are follow-ups that further improve compliance for the
decoder and encoder, by fixing support for commands on both. Patch 11
also makes sure that supported H.264 profiles are exported on MT8173.

Changes since v2:
* Actually compiles (duh),
* Add follow-up patches fixing support for START/STOP commands for the
  encoder, and stateful decoder.
