Sytesm may hang after s2idle on AMD A+A GPU config due to the following
commits:

for reset in S3") https://bugs.launchpad.net/bugs/1968475

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.
