There are QSGMII PHYs which have 4 PHYs embedded and AFAICT they are
defined as 4 separate Ethernet PHY nodes and this would not be quite a
big stretch to represent them that way compared to how they are.

I would recommend doing the same thing and not bend the MDIO framework
to support the registration of "nested" Ethernet PHY nodes.
