[Bug 73539] [Haswell] eDP panel blank screen: link train fails

--- Comment #15 from Markus Blank-Burian <burian at muenster.de> ---
Looking at the dumps, I found, that there are only 2 lanes activated.
Increasing the intel_dp->lane_count to max_lane_count during the initialization
in intel_dp_compute_config resolves this issue and link training succeeds.
