net: dsa: fill phylink's config supported_interfaces member
Add a new DSA switch operation, phylink_get_interfaces, which should fill in which PHY_INTERFACE_MODE_* are supported by given port. Use this before phylink_create to fill phylink's config supported_interfaces member. This allows for phylink to determine which PHY_INTERFACE_MODE to use with SFP modules.
