drm/nouveau/disp: add method to trigger DP link retrain

This moves control of link retraining in response to HPD IRQ to the
KMS driver's HPD IRQ handler.

NVKM still handles checking link status for the moment, this can be
moved to the KMS driver when it takes explicit control of link rate
selection.

v2:
- skip source config on retrain (fixes some retrain failures)
