[PATCH 0/9][SRU][Jammy] Support USB4 DP alt mode for AMD Yellow Carp graphics card

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1953008

[Impact]

USB4 DP alt mode not available on AMD yellow carp.

[Fix]

Several fixing commits from upstream, inclusive of one titled
"drm/amd/display: Fixup previous PSR policy commit" sauced commit to
fix backport problems for commit 9470620e99e9 ("drm/amd/display: Enable
PSR by default on newer DCN").

This also depends on the firmware updates.

[Test Case]

Plug an external monitor with USB Type-C input function to AMD RMB CRB
(which has yellow carp) usbc0 and usbc1.

[Where problems could occur]

The patches revealed multiple dmub firmware versions were skipped. This
might introduce incompatibilities between driver code and the firmware.
