media: allegro: support handling firmware dependent values
Like the message format, also the identifiers in the messages differ between firmware versions. This especially affects the identifier for the codec that shall be used. As the messages used by the driver are now independent from the firmware, we can use the values defined by V4L2 as identifiers in the messages. Convert the V4L2 codec format to the respective firmware value when encoding the messages to binary format instead beforehand.
