Subject: [PATCH v4 4/6] media: qcom: iris: Add hierarchical coding support
for encoder
Add hierarchical coding support for both gen1 and gen2 encoders by enabling
the following V4L2 controls:
H264:
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING,
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING_TYPE,
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING_LAYER
HEVC(gen2 only):
V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_TYPE,
V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_LAYER
