The "IOT EVK" boards are full Snapdragon reference/development kits, not
small sensor-class IoT devices. Like the CRD, the Purwa IOT EVK carries
an on-board embedded controller (on a separate MCU) that handles fan
control, temperature sensors and EC state-change/suspend notifications.
The existing hamoa-iot-evk board already documents the same EC via
qcom,hamoa-iot-evk-ec.
If needed I can expand the commit message to explain this.
