drm/i915/edp: use lane count and link rate from DPCD for eDP

eDP panels are generally designed to support only a single clock and
lane configuration.

    drm/i915: use lane count and link rate from VBT as minimums for eDP

should have started using the optimal link parameters for eDP
panels. Turns out a certain other OS uses DPCD instead of VBT, which
means trusting VBT on this may not be so reliable after all. Follow
suit.
