Subject: [PATCH 4/5] arm64: dts: renesas: r9a07g054: Drop WDT2 node

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

WDT CH2 is specifically to check the operation of Cortex-M33 CPU and if
used from CA55 CPU would result in an unexpected behaviour. Hence drop
WDT2 node from RZ/V2L SoC DTSI.
