dt-bindings: watchdog: renesas,wdt: Document RZ/V2N (R9A09G056) support

Browse Source 
Document support for the watchdog IP found on the Renesas RZ/V2N
(R9A09G056) SoC. The watchdog IP is identical to that on RZ/V2H(P),
so `renesas,r9a09g057-wdt` will be used as a fallback compatible,
enabling reuse of the existing driver without changes.
