watchdog: renesas_wdt: stop when unregistering
We want to go into a sane state when unregistering. Currently, it happens that the watchdog stops when unbinding because of RuntimePM stopping the core clock. When rebinding, the core clock gets reactivated and the watchdog fires even though it hasn't been opened by userspace yet. Strange scenario, yes, but sane state is much preferred anyhow.
