drm/amd/display: Enumerate LTTPR modes
[WHY]
There are three possible modes for LTTPR:
- Non-LTTPR mode, where AUX timeout is 400 us and no per-hop link
training is done
- LTTPR Transparent mode, where AUX timeout is 3200 us and no per-hop
link training is done
- LTTPR Non-Transparent mode, where AUX timeout is 3200 us and per-hop
link training is done
[HOW]
Use an enum instead of a bool to track LTTPR state; modify comparisons
accordingly.
