[PATCH] arm64: dts: renesas: r8a779g0: Add thermal nodes

[Geert Uytterhoeven]

Add device nodes for the Thermal Sensor/Chip Internal Voltage
Monitor/Core Voltage Monitor (THS/CIVM/CVM) and the various thermal
zones on the Renesas R-Car V4H (R8A779G0) SoC.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>
