drm/amd/display: Fix DP LT sequence on EQ fail
[Why]
The number of lanes wasn't being reset to maximum when reducing link
rate due to an EQ failure. This could result in having fewer lanes in
the verified link capabilities, a lower maximum link bandwidth, and
fewer modes being supported.
[How]
Reset the number of lanes to max when dropping link rate due to EQ
failure during link training.
