net: ethernet: sun4i-emac: Support phy-handle property for finding PHYs 

The sun4i-emac uses the "phy" property to find the PHY it's supposed to
use. This property was deprecated in favor of "phy-handle" in commit
8c5b094476 ("dt-bindings: net: sun4i-emac: Convert the binding to a
schemas").

Add support for this new property name, and fall back to the old one in
case the device tree hasn't been updated.
