Allows run-time control over watchdog auto-start and the timeout via setting the environment variable watchdog_timeout_ms. A value of zero means "do not start". Use CONFIG_WATCHDOG_TIMEOUT_MSECS as initial value. Users can enable the watchdog to monitor the boot process until userspace or OS takes over to serve the watchdog.
