drm/amd/display: allow skipping link bandwidth clear
[why]
To set link bandwidth with zero could hit error protection
from Sink panel to fail link training and cause screen

[how]
To skip link bw cleaning in two conditions:
1. eDP v1.5 or latter, because the last write will take effect.
2. Sink requires not to clear it.
