cros_ec hwmon driver probes available thermal sensors when probing the
driver. Register these thermal sensors to the thermal framework as well
via setting HWMON_C_REGISTER_TZ as a chip info, such that thermal
framework can adopt these sensors as well.
To make cros_ec registrable to thermal framework, the cros_ec dts need
the corresponding changes:
&cros_ec {
#thermal-sensor-cells = <1>;
};

Changes in v2:
- Rename `cros_ec_sensor_data` to `cros_ec_hwmon_thermal_zone_data`.
- Rename `addr` in struct `cros_ec_hwmon_thermal_zone_data` to `idx`.
- Use `cros_ec_hwmon_temp_to_millicelsius` to do value conversion in
`cros_ec_thermal_get_temp` function.
- Rename `cros_ec_thermal_get_temp` to `cros_ec_hwmon_thermal_get_temp` to
make `cros_ec_hwmon` a prefix.
- Use `%pe` in `cros_ec_hwmon_probe_temp_sensors` when printing out
`data->tz_dev` if failed register thermal device.
- Remove `cros_ec_hwmon_remove`, and the `.remove` value in
`cros_ec_hwmon_driver` since there is no need to call
`devm_thermal_of_zone_unregister` for clean up.
- Revert function signature of `cros_ec_hwmon_probe_temp_sensors` since all
needed parameters are presented.
- Revert include of `linux/list.h` because no list data structure is used.
---
Changes in v3:
- Revert all changes and just as add HWMON_C_REGISTER_TZ as a chip info.
- Remove unneeded Change-Id tag in commit message.
