I think these two should be orthogonal.

ethernet-phy-idNNNN.NNNN should be used to load the driver. The driver
has a list of IDs it can drive, and we want the module loading
machinery to load a module which can driver this ID.

"ethernet-phy-ieee802.3-c45" should be about how to read the ID
registers, if ethernet-phy-idNNNN.NNNN is not present.
