Restart operation never exists and reset operation never
makes the watchdog expire immediately but expire_now operation
does.

Enable driver model for watchdog timer. At the moment the API
is very simple and only supports four operations:
- start, restart, stop and reset (expire immediately).
+ start, stop, reset and expire_now (expire immediately).
What exactly happens when the timer expires is up to a particular
device/driver.
