drm/amd/display: Skip DPIA-specific DP LL automation flag for non-DPIA links
[Why]
The is_automated flag logic only applies to USB4 DPIA links during DP LL
compliance test automation. The flag should not be set for non-DPIA
cases.
[How]
Add check for DPIA link endpoint type before setting the flag. Also,
rename is_automated to skip_fallback_on_link_loss for clarity.
