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.
