Add support for the ExynosAutoV920 SoC. Basically this is almost
similar to ExynosAuto V9 or Exynos850 such as two watchdog instance for
each cluster but some CPU configuration are quite different.
Therefore device tree, compatibles and drvdata should be added.

- Fix worng variant condition (cl1 -> cl0)
- Move the location declaring watchdog node
  to the correct location that fits the DTS coding rules
