drm/amd/display: Handle downstream LTTPR with fixed VS sequence
[Why]
Several issues were discovered that caused link
training to fail when an LTTPR device is
connected downstream for the fixed VS sequence.
[How]
The following were added:
- workaround to configure AUX timeout
for fixed VS sequence
- additional delay before disabling
fixed VS intercept
- detection of fixed VS deadlock state and
performing DPCD sequence to recover
