thermal/drivers/qcom/tsens-v0_1: Add mdm9607 correction offsets
According to the msm-3.18 vendor kernel from Qualcomm, mdm9607 needs
"correction factors" to adjust for additional offsets observed after the
factory calibration values in the fuses [1, 2].
The fixed offsets should be applied unless there is a special
calibration mode value that indicates that no offsets are needed [3].
Note that the new calibration mode values are called differently in this
patch compared to the vendor kernel:
- TSENS_TWO_POINT_CALIB_N_WA -> ONE_PT_CALIB2_NO_OFFSET
- TSENS_TWO_POINT_CALIB_N_OFFSET_WA -> TWO_PT_CALIB_NO_OFFSET
This is because close inspection of the calibration function [3] reveals
that TSENS_TWO_POINT_CALIB_N_WA is actually a "one point" calibration
because the if statements skip all "point2" related code for it.
