Add devlink integration into the mscc_ocelot switchdev driver. All physical ports (i.e. the unused ones as well) except the CPU port module at ocelot->num_phys_ports are registered with devlink, and that requires keeping the devlink_port structure outside struct ocelot_port_private, since the latter has a 1:1 mapping with a struct net_device (which does not exist for unused ports). Since we use devlink_port_type_eth_set to link the devlink port to the net_device, we can as well remove the .ndo_get_phys_port_name and .ndo_get_port_parent_id implementations, since devlink takes care of retrieving the port name and number automatically, once .ndo_get_devlink_port is implemented. Note that the felix DSA driver is already integrated with devlink by default, since that is a thing that the DSA core takes care of. This is the reason why these devlink stubs were put in ocelot_net.c and not in the common library. It is also the reason why ocelot::devlink is a pointer and not a full structure embedded inside struct ocelot: because the mscc_ocelot driver allocates that by itself (as the container of struct ocelot, in fact), but in the case of felix, it is DSA who allocates the devlink, and felix just propagates the pointer towards struct ocelot.
