Add support for the Thermal Sensor/Chip Internal Voltage Monitor/Core
Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car V4H (R8A779G0) SoC.

According to the R-Car V4H Hardware User's Manual Rev. 0.70, the
(preliminary) conversion formula for the thermal sensor is the same as
for most other R-Car Gen3 and Gen4 SoCs, while the (preliminary)
conversion formula for the chip internal voltage monitor differs.
As the driver only uses the former, no further changes are needed.

Hi Geert,

Thanks for your work.
