net: phy: dp83822: Add support for changing the transmit amplitude voltage

Browse source

Add support for changing the transmit amplitude voltage in 100BASE-TX mode.
Modifying it can be necessary to compensate losses on the PCB and
connector, so the voltages measured on the RJ45 pins are conforming.
