drm/i915/dp: Don't stop the link when retraining
On pre-ddi platforms we don't shut down the link when changing link
training parameters. Except when clock recovery fails too hard and we
restart with channel eq training. Which doesn't make a lot of sense
really, since just stopping/restarting the DP port at this point
violates the modeset sequence documented in the Bspec.
So let's tempt fate and try this.
This patch is motivated by a WARN_ON triggered by
commit bc76e320f21f8bd790a72bd5dc06909617432352
