Wenjing Liu e7f2c80cba drm/amd/display: check hpd before retry verify link cap
[why]
During detection link training if a display is disconnected,
the current code will retry 3 times of link training
on disconnected link before giving up.

[how]
Before each retry check for HPD status, only retry
verify link cap when HPD is still high.
Also put a 10ms delay between each retry to improve
the chance of success.
