From: Dimitri Fedrau <dimitri.fedrau@xxxxxxxxxxxx>
Add property tx-amplitude-100base-tx-gain-milli in the device tree bindings
for configuring the tx amplitude of 100BASE-TX PHYs. Modifying it can be
necessary to compensate losses on the PCB and connector, so the voltages
measured on the RJ45 pins are conforming.
