Thinking about this one more time -- if we ever want to use
dev_priv->edp.lanes, we should use it in
intel_dp_max_lane_count. intel_dp_set_m_n should use
intel_dp->lane_count unconditionally as that's the value we've used
everywhere else for mode setting.
Perhaps we should use it for monitors that don't include the
MAX_LANE_COUNT field in the dpcd? Perhaps we should use it on all eDP
monitors?
