mediatek: consider adc_oe thermal calibration value in efuse

Browse source 
The use of the adc_oe value stored in the efuse has been dropped in
MediaTek's SDK during a recent refactorization of the temperature
calculation formula. Don't ignore this offset value and again include
it in raw-to-deg-celsius calculation.
