I don't think it's a good idea to further extend the usage of this binding. The driver should use the phy-handle property and of_phy_connect() which gives you a proper device node for the phy. Then the phy device node should get the reset gpio. I know it's more work, but doing it like this gives you additional goodies like proper handling of the max-speed property, a fixed-link if necessary and picking the correct phy if there are muliple phys on the bus.
