This prevents PHY not found types of errors for PHY drivers that are probed after the Ethernet driver is probed, because the ifconfig UP is done from userspace after all drivers have been probed. Also avoid the cvmx-helper-board.c PHY code if a real PHY driver is present, this allows a bootloader supplied device tree to specify the PHY information rather than having to modify the code for each different board.
