thermal: amlogic: Add thermal driver to support G12 SoCs
Amlogic G12A and G12B SoCs integrate two thermal sensors
with the same design. One is located close to the DDR controller
and the other one is located close to the PLLs (between the CPU and GPU).
The calibration data for each of the thermal sensors instance is stored
in a different location within the AO region.
Implement reading the temperature from each thermal sensor.
The IP block has more functionality, which may be added to this driver
in the future:
- chip reset when the temperature exceeds a configurable threshold
- up to four interrupts when the temperature has risen above a
configurable threshold
- up to four interrupts when the temperature has fallen below a
configurable threshold
