Subject: [PATCH 05/11] media: cedrus: Filter controls based on capability
Because not all Cedrus variants supports all codecs, controls should be
registered only if codec related to individual control is supported by
Cedrus.
Replace codec enum, which is not used at all, with capabilities flags
and register control only if capabilities are met.
