drm/amd/display: Fix possible infinite loop in DP LT fallback
[Why]
It's possible for some fallback scenarios to result in infinite looping
during link training.
[How]
This change modifies DP LT fallback behavior to more closely match the
DP standard. Keep track of the link rate during the EQ_FAIL fallback,
and use it as the maximum link rate for the CR sequence.
