intel/kunimitsu, google/glados: Enable Fan control support
This patch enables the Fan thermal participant device in the device tree for thermal active cooling action for DPTF on SKL-U fan based kunimitsu board. This patch defines the _ART table in dptf ASL file. With active cooling policy (_ART), we can control the fan on/off and speed. BRANCH=None BUG=chrome-os-partner:46493 TEST=Built for kunimitsu board. Tested to see that the thermal devices and the participants are enumerated and can be seen in the /sys/bus/platform/devices. Also, checked the FAN type the cooling devices enumerated in the /sys/class/thermal with sysfs interface.
