On new Exynos chips (e.g. Exynos850) new CLUSTERx_NONCPU_OUT register is introduced, where CNT_EN_WDT bit must be enabled to make watchdog counter running. Add corresponding quirk and proper infrastructure to handle that register if the quirk is set. This commit doesn't bring any functional change to existing devices, but merely provides an infrastructure for upcoming chips support.

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.
