Add support for being able to set the learning attribute on port, and make sure that the standalone ports start up with learning disabled. We can remove the code in bcm_sf2 that configured the ports learning attribute because we want the standalone ports to have learning disabled by default and port 7 cannot be bridged, so its learning attribute will not change past its initial configuration.
