[PATCH v2] fujitsu-laptop: Unify max brightness of exported leds

[Matej Groma <matejgroma@gmail.com>]

Exported leds had maximum brightness previously unset, thus having
value 255. Set maximum brightness of leds that can only be turned
off or on to 1, making the behavior more consistent with other leds
having binary state.
