[SRU][Hirsute][PULL] Add s2idle support on AMD Renoir and Cezanne

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1927067

[Impact]
S2idle doesn't work on AMD Renoir and Cezanne.

[Fix]
Backport AMD PMC driver and pull many new patches let AMDGPU support s2idle.

[Test]
Suspend the laptop and the system freezes.
With the patch applied, suspend works but with some caveats:
1) Keyboard sometimes can't wake up the laptop.
2) Touchpad sometimes can wake up the laptop.
3) RTC can't wake up the laptop.

[Where problems could occur]
Most changes are limited to logic of suspend/resume, and specific to Renoir GFX.
However, there are some refactoring patches may cause unintended
results, so AMDGPU may break for sleep/hibernation/runtime suspend on
non-Renoir GFXs.
