arm64: dts: renesas: r8a77961: Add thermal nodes 



Add a device node for the Thermal Sensor/Chip Internal Voltage Monitor
in the R-Car M3-W+ (R8A77961) SoC, and describe the thermal zones.

According to the R-Car Gen3 Hardware Manual Errata for Revision 2.00 of
Jan 31, 2020, the thermal parameters for R-Car M3-W+ are the same as for
R-Car M3-W.
