[PATCH v4 6/7] arm64: dts: renesas: r9a09g077: Use CPG/MSSR syscon for WDTDCR access

From: Lad Prabhakar <[email protected]>

The WDTDCR registers for wdt0-wdt5 reside in the second register region of
the CPG/MSSR block. This multi-function block is now exposed via a unified
syscon regmap interface.

Replace the direct mapping of the individual WDTDCR registers with the
new "renesas,sysc" phandle property pointing to the CPG/MSSR block syscon
node.
