This patch updates the EMC2305 hwmon driver to register the thermal
cooling device with Device Tree (DTS) node. This change allows
cooling device to be configured based on the properties defined
in the Device Tree.

The use of a devm_ function means that
for (i = 0; i < EMC2305_PWM_MAX; i++)
if (data->cdev_data[i].cdev)
thermal_cooling_device_unregister(data->cdev_data[i].cdev);
and thus each call to emc2305_unset_tz() will be fatal after this change.
I don't mind the change itself, but emc2305_unset_tz() and all calls to it
will have to be removed as well.
