media: coda: extend GOP size range
CodaDx6 only accepts GOP sizes up to 60 frames, but CODA960 can handle
up to 99 frames. If we disable automatic I frame generation altogether
by setting GOP size to 0, we can let an application produce arbitrarily
large I frame intervals using the V4L2_CID_MPEG_VIDEO_FORCE_KEY_FRAME
control.
