init: remove pulsing led on boot

* Without a reliable way to determine what color to make the led
  if the device is plugged in when powered up based on userspace
  settings which can adjust colors and thresholds for the colors,
  it makes more sense to just disable this 'feature' as it it will
  otherwise cause the pulsing to continue forever.
