…ord PMICs PMAU0102 (Kai_MV) and PMM8650AU's Kobra_MM ADC5 Gen3 controllers only expose REF_GND/1P25VREF/DIE_TEMP calibration channels; none of their AMUX thermistor pins are wired up, so none of the board thermistor rails feed the thermal framework. Only 3 AMUX pins are actually wired to thermistors on Nord, all on Kai and none on Kobra: Kai instance E's AMUX1 (SDRAM3 THERM) and Kai instance I's AMUX1/AMUX2 (SDRAM1 THERM, UFS THERM). Kai's other AMUX pins are either DO_NOT_USE or wired to voltage-rail monitors, not thermistors, so add only these 3 channels. Add #thermal-sensor-cells = <1> to the two Kai adc@ nodes that gain a channel, the new AMUX1[/AMUX2]_THM channel(s) with qcom,adc-tm, and a per-channel thermal-zone for each, following the existing Gen3/Gen4 board pattern of a direct thermal-sensors phandle into the ADC channel.

PENDING: arm64: dts: qcom: nord: add ADC-TM thermal channels for Nord.
Add the 3 thermistor channels confirmed by IPCAT (chipio/systemio/chip/567, NordDC column) for Nord's PMAU0102 (Kai_MV) ADC: SDRAM3_THERM on Kai instance E (AMUX1), and SDRAM1_THERM/UFS_THERM on Kai instance I (AMUX1/AMUX2). No other AMUX pins on Kai are wired to thermistors, and none exist on Kobra_MM, so only these 3 are added. Adds #thermal-sensor-cells = <1> to the two affected adc@7200 nodes, the channel nodes with qcom,adc-tm, and a per-channel thermal-zone with generic hot/critical trips using the standard 100K pull-up default.
