Registers have moved around across TSENS generations. For example, the
CTRL register was at offset 0x0 in the SROT region on msm8916 but is at
offset 0x4 in newer v2 based TSENS HW blocks.
Allow passing offsets of important registers so that we can continue to
use common functions.

Add support to calibrate sensors on 8916 family and also add common
functions to read temperature from sensors (This can be reused on
other SoCs having similar TSENS device)
The calibration data is read from eeprom using the generic nvmem
framework apis.
Based on the original code by Siddartha Mohanadoss and Stephen Boyd.
