thermal/drivers/tsens: Rework legacy calibration data parsers

Rework existing calibration parsing code to use simple data structure
describing data layout. This allows us to drop all the mask & shift
values, replacing them with data tables.

The code for msm8974 is not reworked, as it has separate calibration and
backup data.
