Implement LED color policy (crosbug.com/p/23957)

Update battery vendor information (crosbug.com/p/24684)

BUG=chrome-os-partner:24885
BRANCH=rambi
TEST=manual
  system on, lidclose -> power LED off
  system on, lidopen -> power LED on
  system suspended -> power LED blinks green every 2 sec
  system suspended, lid closed -> power LED off
  system off -> power LED off
  plug AC in, battfake 95 -> charging LED green
  plug AC in, battfake 94 -> charging LED orange
  unplug AC, battfake 10 -> charging LED off
  unplug AC, battfake 9 -> charging LED blinks orange
  battcutoff -> after a few sec, system powered down
  plug back in AC -> system comes back on
  charger -> I_in < 1700
