Ok, so while looking at the upfront link training stuff, it became obvious
that we needs to do something about the link training stuff that we have
in hpd_pulse currently. The thing is, you can't grab any modeset locks from
that work since it could lead to a deadlock with MST sideband stuff.
So here's a quick attempt at moving the stuff over to the hotplug work.

I've included a few other things at the start just to make the
surroundings a little less broken (some of that I've posted before).
And there are a few potentially helpful snippets at the end too.
The main meat is in the middle.

Entire series avaialable here:

Ville Syrjälä (12):
  drm/i915: Ignore initial lid state for eDP
  drm/i915: Read PSR caps/intermediate freqs/etc. only once on eDP
  drm/i915: Avoid mixing up SST and MST in DDI setup
  drm/i915: Reject mixing MST and SST/HDMI on the same digital port
  drm/i915: Track active streams also for DP SST
  drm/i915: Allow MST sinks to work even if drm_probe_ddc() fails
  drm/i915: Move DP link retraining into intel_dp_detect()
  drm/i915: Skip dpcd/edid read unless there was a long hpd
  drm/i915: Remove useless rate_to_index() usage
  drm/i915: Allow rate_to_index() to return non-exact matches
  drm/i915: Don't try to ack sink irqs when there are none
  drm/i915: Add encoder .sync_state() hook
