drm/amd/display: have pretrain for dpia
[WHY]
We like to have pretrain for dpia link so that dp and dp tunneling
have aligned behavior. The Main difficult for dpia pretrain is that
encoder can not get corresponded dpia port when link detection
in current implementation.
[HOW]
1. create enable/disable dpia output functions for dcn35 encoder
and have dpia_id and other necessary info as inputs.
2. dcn35 dpia use the new functions to enable/disable output.
3. have a option to enable/disable the change.
