phy: qcom-qmp-combo: drop lanes config parameter

Since the QMP driver split there is really no need for the 'lanes'
configuration parameter as all of these USB-C PHYs support dual-lane
SuperSpeed USB and quad-lane (uni-directional) DP (even if the driver
still only supports CC1 orientation using lanes 2 and 3).
