This patch was previously part of "[PATCH 07/10] drm/i915: Add structures for
Displayport compliance testing parameters". Adds a struct to maintain link
configuration data for Displayport compliance testing. The members added to
the intel_dp struct are for compliance testing purposes only and should not
be used during normal operations.
