On some systems, the PHY can be internal, in the same package as the
Ethernet MAC, and still be responding to a specific address on the MDIO
bus, in that case, the Ethernet MAC might need to know about it to
properly configure a port multiplexer to switch to an internal or
external PHY. Add a new PHY interface mode for this and update the
Device Tree of_get_phy_mode() function to look for it.
