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. We have to be careful
though, controls have to be tightly packed in ctx->ctrls array.
Otherwise functions cedrus_find_control_data() and
cedrus_get_num_of_controls() won't work properly.
