[SRU] [J] [PATCH 0/1] Fix AMDGPU Navi 10 regression

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1996740

[Impact]
"UBUNTU: SAUCE: Revert "drm/amd/display: Add helper for blanking all dp
displays" caused AMD Navi10 GFX to panic at boot.

[Fix]
Backport the revised version of "drm/amd/display: Add helper for
blanking all dp displays".

[Test]
Users confirmed the issue went away with this fix.
We also verified the original issue we fixed didn't reappear.

[Where problems could occur]
We didn't test all the combination of dce110/dcn10/dcn30/dcn31, so many
cases are untested, hence the potential risk is there.
