watchdog: da9052_wdt: use timeout value from external inputs
Introduce the `timeout` module parameter and pass it to
watchdog_init_timeout(). If the parameter is not set or contains an
invalid value, fallback on the `timeout-secs` devicetree property value.
If none of the above is valid, go for the old default value.
