[ Upstream commit b69713f502027150ecc08e663fa1804d78b3ef42 ]
the firmware only support low latency mode for h264, but firmware will notify an event to driver when one frame is decoded, if V4L2_CID_MPEG_VIDEO_DEC_DISPLAY_DELAY_ENABLE is enabled, and V4L2_CID_MPEG_VIDEO_DEC_DISPLAY_DELAY is set to 0, driver can display the decoded frame immediately.
