ARM: dts: s3c64xx: Fix infinite interrupt in soft mode

Browse Source 
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.
