drm/i915: switch to drm core dp aux helpers

Switch over to using Thierry's drm dp aux helpers.

The previous RFC series (from before the helpers were merged) is at [1]. I specifically decided to dodge the sleep state issues pointed out by Ville [2] for now; this series does not make us better or worse in this regard.

Only briefly tested on SNB, but seems to work.

Patch 1 has been posted and reviewed on dri-devel already [3], and is included here for completeness.

(These patches demonstrate that git format-patch needs a "function rewrite" option... the diffs in patches 4 and 6 turned out quite hideous with mixed + and - lines.)

BR,
Jani.
