[PATCH v3 2/2] dt-bindings: hwmon: pmbus: mps,mpq8785: add #thermal-sensor-cells

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@xxxxxxx>

Each device of this binding has a single temperature sensor: the
internal sensor of its die, which the device also uses for its
over-temperature protection. It is read over PMBus with
READ_TEMPERATURE_1 (8Dh). The sensor is internal, not an input:
none of these devices has a pin for an external temperature sensor.

Allow a thermal zone to use the device as its sensor, to monitor the
regulator's temperature. With a single sensor per device, no cell is
needed.

The MPM82504 has four channels, each with its own PMBus address set by
its own ADDR pin, so each channel is described by its own node.
