drm/amd/display: Restructure dpia link training
[WHY]
We intend to consolidate dp tunneling and conventional dp link training.
[HOW]
1. Use the same link training entry for both dp and dpia
2. Move SET_CONFIG of non-transparent mode to dmub side
3. Add set_tps_notification dmub_cmd to notify tps request for
non-transparent dpia link training
4. Check dpcd request result and abort link training early if dpia
aux tunneling fails
5. Add option to avoid affect old product
6. Separately handle wait_time_microsec for dpia
