fe4b8c98dd drm/amd/display: un-block 8k with single dimm 
[Why]
Driver doesn't validate multi-display with scaling when OS calls DDI.
This behavior causes the validated result to be a mismatch
between some automated test cases.
To address this issue, some workaround was added that caused issues in 8k.

[How]
Since the origin issue had been root caused,
revert the previous workaround and unblock 8k with a single dimm.
