intel/skylake: Add Fan control support
This patch adds the ASL file for Fan as cooling device
/participant for thermal active cooling action for DPTF
on SKL-U fan based kunimitsu board.
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.
