Matti Vaittinen e3b3afd34d watchdog: bd9576: Drop "always-running" property 
The always-running (from linux,wdt-gpio.yaml) is abused by the BD9576
watchdog driver. It's defined meaning is "the watchdog is always running
and can not be stopped". The BD9576 watchdog driver has implemented it
as "start watchdog when loading the module and prevent it from being
stopped".

Furthermore, the implementation does not set the WDOG_HW_RUNNING when
enabling the watchdog due to the "always-running" at module loading.
This will end up resulting a watchdog timeout if the device is not
opened.

The culprit was pointed out by Guenter, discussion can be found from
https://lore.kernel.org/lkml/4fa3a64b-60fb-4e5e-8785-0f14da37eea2@roeck-us.net/

Drop the invalid "always-running" handling.
