Adjust the training sequence.Detects the actual link condition
and calculates the bandwidth where the relevant resolution resides.
The bandwidth is recalculated and modes that exceed the bandwidth are
filtered.

This is giving the same values as drm_dp.h, hence unneeded.

This commit is not even based on upstream, so you haven't even tested it upstream.
Don't send untested commits.
