media: v4l2-ctrls: validate HEVC EXT SPS RPS counts
The HEVC SPS control carries the short-term and long-term RPS counts
that decoder drivers use to walk the matching EXT SPS dynamic arrays.
Reject SPS values that exceed the HEVC limits of 64 short-term sets and
32 long-term references so drivers cannot later index beyond those
controls.
Also reject EXT SPS ST RPS entries whose negative or positive picture
counts exceed the 16-entry arrays, or whose combined delta-POC count
exceeds the HEVC DPB maximum.
Fixes: c9a59dc2acc7 ("media: rkvdec: Add HEVC support for the VDPU381 variant")
