tps61310: Move flashlight_off to suspend handler

* Early suspend is kind of stupid in this driver, move the call to
  flashlight_off to the full suspend handler instead.
* This should let the flashlight remain on when the display is inactive,
  by having userspace grab a PARTIAL_WAKE_LOCK if needed.
