But it is ok for an external interface to use the 'lane_mode' name.

The lane mode of HCCS port is an information to user, and actually comes from the maximum lane number. But it is good and easy for driver to use the maximum lane number. So fix the 'lane_mode' field name in port info structure to 'max_lane_num'.
