ionic: add FW_STOPPING state
Between fw running and fw actually stopped into reset, we need a fw_stopping concept to catch and block some actions while we're transitioning to FW_RESET state. This will help to be sure the fw_up task is not scheduled until after the fw_down task has completed. On some rare occasion timing, it is possible for the fw_up task to try to run before the fw_down task, then not get run after the fw_down task has run, leaving the device in a down state. This is possible if the watchdog goes off in between finding the down transition and starting the fw_down task, where the later watchdog sees the FW is back up and schedules a fw_up task.
