thermal/drivers/airoha: Add support for AN7583 Thermal Sensor

Browse source

Add support for Airoha AN7583 Thermal driver. This apply similar logic
on how to read the temperature but totally drop support for the
PTP_THERMAL subsystem. PTP_THERMAL subsystem was a way to trigger trip
point from hardware by configuring how to read the temperature
internally.

This subsystem has been totally removed from Airoha AN7583 permitting
only to read the temperature.

The SoC support up to 3 sensor but the original driver always read the
BGA sensor hence it's currently implemented reading only this specific
sensor. Reference and values for the other 2 sensor are defined for
further implementation if confirmed working.

set_thermal_mux() is extended to also address muxing the sensor as
AN7583 use a different way to read the temperature from 3 different
diode. The EN7581 code is updated to account for these changes.
