Xorg log from failure case (same 5.9-next kernel)

Xorg.log from trying to run Xorg under kernel that fails to set resolutions
properly. The DisplayPort-0 displays at 1024x768, and I can not set the
resolution any higher than that from within Xorg (using the enlightenment
"screen" settings panel).

You can see from the following line that it boots into 1024x768:
[    38.608] (II) AMDGPU(0): Output DisplayPort-0 using initial mode 1024x768
+0+0
