watchdog: w83627hf_wdt: Use WDOG_HW_RUNNING for running chip on boot

Browse Source 
If the watchdog is already running when the driver is initialized, the
driver currently refreshes it once using the default timeout of 60
seconds.

Since commit ee142889e3 ("watchdog: Introduce WDOG_HW_RUNNING flag"),
the watchdog core can kick an already running watchdog alive until
userspace open the device.

Add the WDOG_HW_RUNNING flag to the watchdog status if the watchdog is
already running.
