[pull] amdgpu drm-fixes-5.8 (take 2)

[Alex Deucher]

Hi Dave, Daniel,

A few fixes for 5.8.  It would be nice to get these in for 5.8 final.  Take
2 just reverts the original fix because the fix for the fix seems to cause
other problems.

The following changes since commit a4a2739beb8933a19281bca077fdb852598803ed:
