arm64: dts: renesas: r9a09g057: Remove wdt{0,2,3} nodes

The HW user manual for the Renesas RZ/V2H(P) SoC (a.k.a r9a09g057)
states that only WDT1 is supposed to be accessed by the CA55 cores.
WDT0 is supposed to be used by the CM33 core, WDT2 is supposed
to be used by the CR8 core 0, and WDT3 is supposed to be used
by the CR8 core 1.

Remove wdt{0,2,3} from the SoC specific device tree to make it
compliant with the specification from the HW manual.

This change is harmless as there are currently no users of the
wdt{0,2,3} device tree nodes, only the wdt1 node is actually used.
