The NTC thermistor sensor in drivers/sensor/ntc_thermistor/ntc_thermistor.c
cannot work with a 16-bit ADC.
The voltage becomes negative if the ADC raw value is 0x8000 or higher.
To correct this, I changed the types in the
ntc_thermistor_data struct from int16_t to int32_t.
This also corrects a potential problem at line 53
where we transform an int16_t into an int32_t.
