Implement the get_antenna and set_antenna callback functions, which will allow clients to control the antenna for all non-11n hardware (Antenna handling in rt2800 is still a bit magical, so we can't use the set_antenna for those drivers yet). To best support the set_antenna callback some modifications are needed in the diversity handling. We should never look at the default antenna settings to determine if software diversity is enabled. Instead we should set the diversity flag when possible, which will allow the link_tuner to automatically pick up the tuning.
