thermal: sun8i: add TEMP_CALIB_MASK for calibration data in sun50i_h6_ths_calibrate
For sun50i_h6_ths_calibrate(), the data read from nvmem needs a round of calculation. On the other hand, the newer SOC may store other data in the space other than 12bit sensor data. Add mask operation to read data to avoid conversion error.
