Bug description:
[Impact]
DP tunneling over USB4 requires additional work in the AMD GPU driver that
isn't present in 5.14 or 5.15. The code is included in 5.16 kernel and will
need to be backported into 5.14 OEM kernel (and jammy/5.15) to support any
programs that need it.
[Fix]
Cherry-pick/backport 30 commits from 5.16 to 5.15. OEM-5.14 needs a few
additional ones from 5.15.
[Test case]
WIP
