Bug description:
[Impact]
Sytesm may hang after s2idle on AMD A+A GPU config due to the following
commits:
8b328c64c7082278c888927f00e526786eec2880 ("drm/amdgpu: don't use BACO
for reset in S3") https://bugs.launchpad.net/bugs/1968475
a26d80ba0d9e67ea11cbfc25618320163497d3fe ("drm/amd/pm: keep the BACO
feature enabled for suspend") https://bugs.launchpad.net/bugs/1958371
[Fix]
Revert one commit and don't reset dGPU when s2idle
[Test]
Verified on AMD RMB, stress s2idle passed.
[Where problems could occur]
Low risk, it may break s2idle on AMD platform.
