Changes since v1 include: * change the new pixel format to V4L2_PIX_FMT_HEIF_HEVC (1/6). * created a new HEIF control class and control IDs (2/6). * add two additional steps in stateful encoder spec (3/6). * improve the Venus image encoder (4/6 - 6/6). Comments are welcome. First version can be found at: https://lwn.net/ml/linux-media/20210429132833.2802390-1-stanimir.varbanov@linaro.org/
