[PATCH v2 1/3] media: iris: add Long-Term Reference control support for ar50lt encoder

[Vishnu Reddy]

From: Gourav Kumar <gouravk@xxxxxxxxxxxxxxxx>

Add Long-Term Reference(LTR) frame support for ar50lt gen2 encoder by
enabling the following V4L2 controls:
V4L2_CID_MPEG_VIDEO_LTR_COUNT
V4L2_CID_MPEG_VIDEO_USE_LTR_FRAMES
V4L2_CID_MPEG_VIDEO_FRAME_LTR_INDEX
The ar50lt gen2 firmware supports the corresponding LTR HFI properties.
