thermal/drivers/renesas/rzg3e: Add thermal driver for the Renesas RZ/G3E SoC 

The RZ/G3E SoC integrates a Temperature Sensor Unit (TSU) block designed
to monitor the chip's junction temperature. This sensor is connected to
channel 1 of the APB port clock/reset and provides temperature measurements.

It also requires calibration values stored in the system controller registers
for accurate temperature measurement. Add a driver for the Renesas RZ/G3E TSU.
