[PATCH v2 3/4] dt-bindings: watchdog: da9062: add watchdog timeout mode

Document the watchdog timeout mode property. If this property is used
the user can select what happens on watchdog timeout. Set this property
to 1 to enable SHUTDOWN (the device resets), set it to 0 and the device
will go to POWERDOWN on watchdog timeout.
