phy-mode is about the bus between the MAC and the PHY. Internal means
there is not a standard bus between the MAC and the PHY, something
proprietary is being used to embed the PHY in the MAC.
If you are using RMII or RGMII, then it is not internal, in that as
standard bus is being used. It does not matter if that bus is not
available external to the SoC, it still exists.
