thermal/drivers/rcar_gen3: Add support for R-Car V4M

Add support for the Thermal Sensor/Chip Internal Voltage Monitor/Core
Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car V4M (R8A779H0) SoC.

The conversion formulas for R-Car V4M are the same as for other R-Car
Gen4 SoCs.

Based on a patch in the BSP by Duy Nguyen.
