Subject: [PATCH] ampere-av1 Phase 2 step 2: advertise VAProfileAV1Profile0 via
 libva
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extended any_fd_supports_output_format() with vpu981 fd as 4th probe
target. Added V4L2_PIX_FMT_AV1_FRAME advertisement in
RequestQueryConfigProfiles. VAProfileAV1Profile0 in entrypoints +
GetConfigAttributes switches.

V4L2_REQUEST_MAX_PROFILES=11 now exactly full; comment added warning
about future profile additions needing the constant bumped.

Verified via vainfo:
  VAProfileMPEG2Simple/Main, H264×5, HEVC, VP8, AV1   — all advertised
  (VP9 absent because rkvdec module is on sibling-campaign-close
   state, not the broken vp9-iter1; restoring VP9 needs the
   ampere-vp9-enablement campaign reopened or the fail-state module
   reloaded.)
