media: rkvdec: h264: Support profile and level controls

The Rockchip Video Decoder used in RK3399 supports H.264 profiles from Baseline to High 4:2:2 up to Level 5.1, except for the Extended profile. Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE and the V4L2_CID_MPEG_VIDEO_H264_LEVEL control, so that userspace can query the driver for the list of supported profiles and level.
