drm/amd/display: do not read link setting if edp not connected
[Why]
Previously assume eDP sink present if connector present. Do not
need to enforce this restriction. Fix issue where driver attempt
to read link setting even though no edp connected.
{How]
Only read link setting after reading connection status.
