Subject: lights: Make sure the lights are out

 * Annoying situation where the battery charging LED comes on in
   the crypto startup screen, but never gets turned off because
   of caching.
 * Explicitly turn off LEDs after the bootanimation completes, and
   always set the full state to the hardware on the first call
   regardless if it's all zeros.
