The patches mentioned in the commit message add _some_ support for
the Cortina PHYs - mainly checking for devices at additional
locations. Once they are found, the phy IDs must be read from custom
locations.

 
As a general principle, we don't add hacks in generic code to handle
broken devices. We add generic mechanisms to work around the
brokenness.

In this case, by using ethernet-phy-id in the device tree, we are
saying, this PHYs probing is totally borked, but we know it is there,
at this address. Just load the driver.

Please try to make ethernet-phy-id work.
