thermal: msm8974-tsens: Fix incorrect temperature readings

There are two different versions for the one point calibration.
One using the method point1_10bit = ((base_8bit << 2) | 0x2)
+ point1_6bit and the second point1 calibration method is
point1_10bit = ((base_8bit + point1_6bit) << 2) | 0x2. The
one point calibration was incorrectly referencing to the first
point calibration for the corresponding calibration mode from
the efused bits.
