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
8c5b09447625 ("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.

The aforementioned commit is in v5.3-rc1. It would be nice to have the
driver fix in the same release. In addition, an update for the device
tree has been queued up for v5.4, which made us realize the driver needs
an update.
