Quentin Schulz 71e32a20cf net: mscc: ocelot: make use of SerDes PHYs for handling their configuration
Previously, the SerDes muxing was hardcoded to a given mode in the MAC
controller driver. Now, the SerDes muxing is configured within the
Device Tree and is enforced in the MAC controller driver so we can have
a lot of different SerDes configurations.

Make use of the SerDes PHYs in the MAC controller to set up the SerDes
according to the SerDes<->switch port mapping and the communication mode
with the Ethernet PHY.
