[PATCH v2] drm/amd/display: dp debugfs allow link rate lane count greater than dp rx reported caps

[Harry Wentland]

From: Hersen Wu <hersenxs.wu at amd.com>

[Why]
when hw team does phy parameters tuning, there is need to force dp
link rate or lane count grater than the values from dp receiver to
check dp tx. current debufs limit link rate, lane count no more
than rx caps.

[How] remove force settings less than rx caps check

v2: Fix typo in title
