net: stmmac: fill in supported_interfaces
Fill in phylink's supported_interfaces bitmap with the PHY interface modes which can be used to talk to the PHY. We indicate that the PHY interface mode passed in platform data is always supported, as this is the initial mode passed into phylink. When there is no PCS specified, we assume that this is the only mode that is supported - indeed, the driver appears not to support dynamic switching of interface types at present. When a xpcs is present, it defines the PHY interface modes that the stmmac driver can support. Request the supported interfaces from the xpcs driver, and pass them to phylink.
