[PATCH v2 6/8] ARM: dts: exynos: Fix infinite interrupt in soft mode on Exynos4210 and Exynos5440

In soft (no-reboot) mode, the driver self-pings watchdog upon expiration
of an interrupt. The interrupt has to be cleared, because otherwise
system enters infinite interrupt handling loop.
Use a samsung,s3c6410-wdt compatible to select appropriate quirk for
clearing the watchdog interrupt.
