This adds support for enabling the internal PHY for a 'cpu' port. It has been tested on GE B850v3, B650v3 and B450v3, which have a built-in MV88E6240 switch hardwired to a PCIe based network card. On these machines the internal PHY of the i210 network card and the Marvell switch are connected to each other and must be enabled for properly using the switch. While the i210 PHY will be enabled when the network interface is enabled, the switch's port is not exposed as network interface. Additionally the mv88e6xxx driver resets the chip during probe, so the PHY is disabled without this patch.
