Implement triggers inside rt2x00 itself based on input from mac80211. This replaces the method of using the mac80211 trigger events which do not work for USB drivers due to the scheduling requirement. After this patch RT2500USB_LEDS and RT73USB_LEDS no longer need to be tagged as broken since they now support LED handling again without having to check for in_atomic().
