With the phy_port infrastructure came an ethernet-connector binding, allowing to represent the MDI of a PHY in devicetree. This allows specifying the mediums and pairs of a port. Let's initialize the port's supported list based on what the PHY reports, so that we can then filter it with what the connector allows using.
