arm64: dts: renesas: rzg2l: Drop WDT2 nodes
On members of the RZ/G2L family, WDT CH2 is specifically meant to check
the operation of the Cortex-M33 CPU. Using it from a Cortex-A55 CPU
would result in unexpected behaviour. Hence drop all WDT2 nodes and
their references from the affected SoC and SoM DTSI files.
