Bug Description

[Impact]
Some Laptops use suspend-to-idle freeze at resume.

[Fix]
Delay after PCI power transition completion on suspend-to-idle, just like runtime resume.

[Test]
With the patch applied, the system can pass suspend stress test.

[Regression Potential]
Low. It's a stable patch that's already in Eoan/Focal kernel.
