watchdog: starfive: check watchdog status before enabling in system resume
System resume will start and enable watchdog regardless of whether the
watchdog is enabled/disabled during a system suspend.
Add a check to the watchdog status and only start and enable the
watchdog if the watchdog status is running/active.
