[PATCH v4 3/3] watchdog: w83627hf_wdt: Use WDOG_HW_RUNNING for running chip on boot

[Paul Louvel]

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 ee142889e32f ("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.
