Add dt-bindings description of the thermal sensors in the A523 processor.

The calibration data for both thermal controllers (THS0, THS1) is split
across two nvmem cells at different offsets, requiring the two cells
to be read and merged. To maintain backward compatibility, the name of
the old cell remains "calibration" and the new cell is named
"calibration-second-part".
