[PATCH v5 1/3] dt-bindings: embedded-controller: Add Lenovo ThinkPad T14s thermal sensor provider support

[Daniel Lezcano <daniel.lezcano@oss.qualcomm.com>]

Document the Lenovo ThinkPad T14s Embedded Controller as a thermal
sensor provider by adding the '#thermal-sensor-cells' property.

This allows the EC temperature sensors to be referenced from thermal
zones in the device tree.
