dt-bindings: watchdog: samsung-wdt: Add exynos990-wdt compatible 



Add a dt-binding compatible for the Exynos990 Watchdog timer.
This watchdog is compatible with the GS101/Exynos850 design, as
such it requires the cluster-index and syscon-phandle properties
to be present. It also contains a cl2 cluster, as such the
cluster-index property has been expanded.
