[PATCH v2 02/28] drm/i915/dp: Add struct intel_dp_link_config

[Imre Deak <imre.deak@intel.com>]

Add a struct representing the public unpacked format of a link
configuration. This will be used by the DP link capability API added
as a follow-up, and by DP code in general that needs to track a link
configuration.
