[PATCH] Revert "drm/amd/display: edp do not add non-edid timings"

[Hersen Wu]

This change causes regression when eDP and external display in mirror
mode. When external display supports low resolution than eDP, use eDP
timing to driver external display may cause corruption on external
display.

This reverts commit aa9704d5127f06c9ffedb0480d2788b87fecedfb.
