Port thermal zones definitions from msm-4.19 tree. Enable and add
channel configuration to PMIC's ADC-TM definitions. Declare thermal
zones and respective trip points.

Unlike other PMIC/tsens thermal zones, these definitions are quite
specific to the board from my point of view.

It is not about this PMIC, but rather about particular thermistors
being placed up in different places on the board itself.
