From: Dimitri Fedrau <dimitri.fedrau@xxxxxxxxxxxx>
Add property mac-series-termination-ohms in the device tree bindings for
selecting the resistance value of the builtin series termination resistors
of the PHY. Changing the resistance to an appropriate value can reduce
signal reflections and therefore improve signal quality.
