Enable Adaptive Sync SDP for Panel replay + auxless ALPM.
First few patches are fixes in existing AS SDP enablement and drm core
changes for Panel replay with SDP.
Later patches add the support to send AS SDP for Panel replay with Link
ON and with auxless ALPM (Link-Off). 

This series is in continuation from discussions in [1] [2] [3]
and is actually revision 5 of the series [4].

While sending patches Rev 3 of [4], patchwork encountered an issue and
somehow dropped few patches from the series, and created new patchwork
links with incomplete list of patches for rev 3 and 4. With this CI couldnt
pick up the series for testing.

To avoid further confusion and more patchwork links with missing patches,
I am modifying the subject of the series to create new 'final' patchwork
link (with a hope that patchwork doesn't miss anymore patches) for which
we can get the CI results.

As the first few drm core changes get reviews, I intend to send those
separately and get them merge next.

Changes from last revision of Series [4]
 - Add helper to print SDP version in the logs and use it.
 - Fill missing sdp_type field in AS SDP unpack.
 - Check PR support also in helper
   intel_psr_pr_async_video_timing_supported()
 - Add #TODO to check Display ID 2.0 blocks for AS SDP for determining
   AS SDP v2 support.
 - Check if PR is enabled along with AS SDP enable before setting
   relevant Downspread CTRL DPCD bits.

Rev 5:
 - Since all DRM core changes and PCON related fixes are merged, rebase
   the remaining patches.
