The Armada XP GP isn't using rgmii-id connections between the MAC and
PHY, but instead a single QSGMII connection, which is a quad-SGMII
connection: a double pair of differential lines that are multiplexed
to convey the traffic of four network interfaces between a MAC and a
PHY.

Until now, the Armada XP GP was relying on the bootloader setting the
correct values in various configuration registers. With this change,
the mvneta driver can be used as a module on this platform.
