sixaxis: Add support for setting LEDs when connected over USB
sixaxis: Add support for setting LEDs when connected over USB

This allows to setup LEDs when device is connected over USB, not
Bluetooth. This coverts two scenarios:
- user plugged PS3 controller and pressed PS3 button before unplugging,
  in that case LEDs are set
- user plugged already BT connected PS3 controller to USB, this results
  in new /dev/input/jsX device being create but controller is still
  transmitting over BT and old jsX device exists. In that case don't
  set LEDs as they are already set.

This is not directly related to Bluetooth itself but change is really
small and provides much better and consistent user experience.
