Li Jun 7cb575b71a watchdog: da9063: fix suspend/resume handling of HW_RUNNING watchdog ...

da9063_wdt_suspend() and da9063_wdt_resume() only check watchdog_active(),
when the watchdog is left running by the driver sets
WDOG_HW_RUNNING in da9063_wdt_probe() but userspace never opens the
device, so WDOG_ACTIVE remains cleared, the wdt_disable() will not be
executed in da9063_wdt_suspend. In this case, the suspend callback is
a no-op and the watchdog keeps counting during system suspend,
leading to an unexpected system reset.
Check WDOG_HW_RUNNING and wdd，can fix this issue.

Fixes: a7ceca4398 ("watchdog: da9063: optionally disable watchdog during suspend")
