arc_emac: remove custom "max-speed" parsing code
The ARC emac driver was the only in-tree to parse a PHY device
'max-speed' property but yet failed to do it correctly because
'max-speed' is supposed to set a PHY device supported features, not the
advertising features as it was done.
Now that of_mdiobus_register() takes care of doing that, remove the
custom 'max-speed' parsing code.
