Now that pcs-lynx supports 1000BASE-X, add support for this interface mode to dpaa2-mac. pcs-lynx can be switched at runtime between SGMII and 1000BASE-X mode, so allow dpaa2-mac to switch between these as well. This commit prepares the ground work for allowing 1G fiber connections to be used with DPAA2 on the SolidRun CEX7 platforms.
