The PHY uses an external 25MHz crystal, and has the SoC's PJ16 pin connected to its reset pin. Enable the second Ethernet port. Also fix up the label for the existing external PHY connected to the first Ethernet port. An enable delay for the PHY supply regulator is added to make sure the PHY's internal regulators are fully powered and the PHY is operational.
