drivers/intel/dptf: Add missing Scope operator for _FIF
Missed one other scope operator in the DPTF cleanup. This one is for the
fan device, and without this fix, the kernel isn't able to properly
control the fan (it gets confused about whether it's ACPI 4+ compatible
or not).
BUG=b:149722146
TEST=verify /sys/class/thermal/cooling_zone0/max_state returns > 1,
and /sys/class/thermal/cooling_zone0/cur_state is writable, and writing
the value of `max_state` causes the fan to spin faster.
