TWL4030: make LEDs selectable for twl4030_led_init()

Browse Source 
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.
