Not all boards have both LEDs hooked, so enabling both on boards with single LED will just waste power. Make it possible to choose LEDs by adding argument to twl4030_led_init(). Using this turn on only LEDB for pandora, leave both LEDs on for all other boards, as it was before this patch. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com>
