media: rkvdec: hevc: tighten EXT SPS RPS control dimensions
The VDPU381 HEVC driver registers V4L2_CID_STATELESS_HEVC_EXT_SPS_ST_RPS
and V4L2_CID_STATELESS_HEVC_EXT_SPS_LT_RPS with .cfg.dims = { 65 }, but
the HEVC spec caps num_short_term_ref_pic_sets at 64 (ITU-T H.265 7.4.8)
and num_long_term_ref_pics_sps at 32 (7.4.3.2.1). The hardware descriptor
table (struct rkvdec_rps) sizes match those spec limits: refs[32] and
short_term_ref_sets[64].
Reduce the dims to { 64 } and { 32 } respectively so the V4L2 control
framework rejects oversized payloads before any driver code runs.
