watchdog: intel-mid_wdt: Add WATCHDOG_NOWAYOUT support

Browse source 
Normally, the watchdog is disabled when /dev/watchdog is closed, but if
CONFIG_WATCHDOG_NOWAYOUT is defined, then it means that the watchdog should
remain enabled. So we should keep it enabled if CONFIG_WATCHDOG_NOWAYOUT
is defined.
