[PATCH v4 1/2] dt-bindings: watchdog: renesas,wdt: Document RZ/V2H(P) SoC

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Add support for the Watchdog Timer (WDT) hardware found in the Renesas
RZ/V2H(P) SoC to the `renesas,wdt` device tree bindings. The RZ/V2H(P)
SoC features a WDT that is compatible with existing Renesas watchdog
drivers.
