The Hantro and Cedrus drivers work in frame-mode, meaning they expect all the slices in a picture (either frame or field structure) to be passed in each OUTPUT buffer. These two are the only V4L2 MPEG-2 stateless decoders currently supported. Given the VA-API drivers also work per-frame, coalescing all the MPEG-2 slices in a buffer before the decoding operation, it makes sense to not expect slice-mode drivers and therefore remove V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMS. This is done to avoid carrying an unused interface. If needed, this control can be added without breaking backwards compatibility. Note that this would mean introducing a enumerator control to specify the decoding mode (see V4L2_CID_STATELESS_H264_DECODE_MODE).
