hwmon: qpnp-adc-voltage: Add version check for case_therm channel

Browse source 
case_therm channel is used for reading the skin temperature.
Calibration type for above thermistor channel has to be absolute
for PM8950 1.0 and ratiometric for PM8950 2.0. Add version check to
detect the PMIC used and update the calibration type accordingly.
