Strictly speaking, it should be neither in the UCC node nor the PHY
node, as it describes the connection between the two, but..

the UCC driver utilizes the data itself; the UCC, unlike other network
controllers, does not provide interface data in its programming model.

the phy drivers are not of_ drivers.  Porting phylib drivers to be of_
drivers would break phylib for non-OF arches, e.g. x86.
