hwmon: pm8xxx-adc: Update pa_therm mapping table
Inaccurate temperature readings are reported for pa_therm when read from the apps. This is because an inaccurate B constant was used while calculating the voltage to temperature mapping table. Fix it by generating the table using the correct B constant for the thermistor.
