Subject: [PATCH v3 0/2] media: Add HEVC long and short term ref pic sets controls

New v4l2 controls for HEVC are added to be able to send the missing long
and short term RPS information to the driver.

Both controls have a dynamic size to send up to 65 sets each.

The controls take raw data as they are read from the video stream.

Changes since v2:
 - Fix long lines
 - Add videodev2.h.rst.exceptions entries
 - Add v1 changes

Changes since v1:
 - Separate long and short term in different controls
 - Use raw data to let drivers format the data how they want
 - doc: Add array information
