Matti Vaittinen d47f51eb1f watchdog: bd9576: Drop "always-running" property 
[ Upstream commit e3b3afd34d ]

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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
