Subject: [PATCH] riscv: dts: renesas: rzfive-smarc-som: Enable WDT

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

Enable WDT node on RZ/Five SMARC SoM.

Note, WDT block is enabled in RZ/G2UL SMARC SoM DTSI [0] hence deleting
the disabled node from RZ/Five SMARC SoM DTSI enables it here too as we
include [0] in RZ/Five SMARC SoM DTSI.

Note,
- For the WDT to correctly on RZ/Five we need a fixup patch [0].
- Patch applies on top of [1]
