Subject: [PATCH v7 09/17] media: rkvdec: Add variant specific coded formats list
Prepare for adding new variants of the decoder and support specific
formats and format ops per variant.
This removes the need of capability flags for variants, so remove them.
Tested-by: Diederik de Haas <didi.debian@...ow.org> # Rock 5B
