net: dpaa2-mac: add 1000BASE-X support
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.
