Bug description:
[Impact]
With WX3200 and 20.04d kernel the unit freezes on resume
[Fix]
commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default") enabled ASPM
by default but a variety of hardware configurations it turns out that this
caused a regression.
Multiple SKUs with wx3200&rx540 gpus encounter the resume&hange issue.
Before the real fix is landed, revert commit 0064b0ce85bb first.
[Test Case]
1. plug wx3200 on the adl machine and make it as a output.
2. suspend&resume machine
3. check if machine could resume successfully
[Where problems could occur]
Low, don't make AMDGPU ASPM by default.
