boot log showing EDID failure

When connecting one of my monitors to the system it defaults to 1024x768 and
not the native resolution and grepping through the kernel logs shows that
AMDGPU fails to read the EDID of the display.

[    5.054779] [drm:dc_link_detect [amdgpu]] *ERROR* No EDID read.

The display was working fine as of kernel 4.18.18 with the issues arising upon
4.19.2.

I am using a POLARIS 10 GPU and both displays are connected to DisplayPort with
the Asus PG2780 having the issues with failing to grab the EDID.
