[PATCH] dt-bindings: watchdog: atmel: Add missing 'interrupts' property

[Rob Herring]

With 'unevaluatedProperties' support implemented, the atmel,sama5d4-wdt
example has the following warning:

/home/rob/proj/git/linux-dt/.build-arm64/Documentation/devicetree/bindings/watchdog/atmel,sama5d4-wdt.example.dt.yaml: watchdog at fc068640: Unevaluated properties are not allowed ('interrupts' was unexpected)

Document the missing 'interrupts' property.
