net: dsa: Add setter for SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS
In preparation for removing SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT, add support for a function that processes the SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS and SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS attributes and returns not supported for any flag set, since DSA does not currently support toggling those bridge port attributes (yet).
