commit c02734d6e4ceaf4cec3e5ec0aa17ca66e9bc280d upstream.

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.
