rt2x00: Cleanup mode registration
Don't wildly pass any number for num_rates to rt2x00lib, instead pass which type of rates are supported (CCK, OFDM). Same for num_modes but then for the 2GHZ and 5GHZ band. This makes the interface look much nicer and makes extending it later easier. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
