Add ADC support for the Renesas RZ/G3S SoC. The key features of this IP
include:
- 9 channels, with one dedicated to reading the temperature reported by the
  Thermal Sensor Unit (TSU)
- A different default ADCMP value, which is written to the ADM3 register.
- Different default sampling rates
- ADM3.ADSMP field is 8 bits wide
- ADINT.INTEN field is 11 bits wide

Hi Claudia,

This one and the others I haven't comment on look good to me.

Thanks,

Jonathan
