Subject: [PATCH net-next v5 01/13] net: phy: initialize the port support based on the PHY's for OF ports

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.
