drm/amd/display: improve dpia pre-train
[WHY]
We see unstable DP LL 4.2.1.3 test result with dpia pre-train. It is
because the outbox interrupt mechanism can not handle HPD
immediately and require some improvement.
[HOW]
1. not enable link if hpd_pending is true.
2. abort pre-train if training failed and hpd_pending is true.
3. check if 2 lane supported when it is alt mode
