I'll move it to the phy node.

There is no device to identify when the controller connects. The PHY's
MDIO bus is registered by the driver that loads its firmware, seconds
later, so phy-handle points at nothing yet. The chip does answer a
Clause 45 identifier before the firmware runs, I read it on my board, so
identification is not the blocker.

Nothing carries firmware-name here, the blob names are in the driver. I
can add it to the phy node and key off that instead. Which do you want
in v2?
