AMD APU s2idle is broken after the ASIC reset fix

[Kai-Heng Feng]

[Impact]
The AMD based system can not reach s2idle after fix for LP: #1968475.

[Fix]
No need to evict resources for s2idle case.

[Test]
Test on a Cezanne, confirmed the 5.14.0-1035 breaks s2idle, and applying
the fix can make s2idle work again.

[Where problems could occur]
The fix only applies to AMD APU, and the resources sould stay at carved
out region over sleep.
