arm64: dts: renesas: r9a09g056: Remove wdt{0,2,3} nodes

The Renesas RZ/V2N SoC (a.k.a. r9a09g056) comes with 4 CA55
cores and 1 CM33 core.

While the user manual doesn't explicitly specify which cores
should have access to particular watchdogs, it turns out that
(similarly to the Renesas RZ/V2H(P)) it only makes sense for
Linux to use WDT1.

Remove DT nodes wdt{0,2,3} from the RZ/V2N SoC specific dtsi
to make it compliant with the original design intent.

This change is harmless as there are no users for the nodes
being stripped out of this device tree.
