[Intel-gfx] [PATCH 08/10] drm/i915: use the new dp train delay helpers

[Daniel Vetter]

Only really required for dp 1.2. I've hoped this would help with some
link training woes I'm fighting, but alas those are only dp 1.1
devices.

Also move a comment that went misplaced in the recent refactorings to
the right spot again.
