IPQ5332 has tsens v2.3.3 peripheral. This patch adds the tsense
node with nvmem cells for calibration data.

Previously you had data for other sensors here. Are they not used at all, not wired, have no known-good placement? I think it might be better to declare all sensors here (and in the driver too) and then consider enabling only a pile of them in the thermal-zone node.

Remaining sensors are not used at all. It is not wired. Only above sensors are placed in SoC.
