dptf: Add support for Fan Performance States
This change adds support for generating the _FPS table for the DPTF Fan
object. The table describes different levels of fan activity that may be
applied to the system in order to actively cool it. The information
includes fan speed at a (rough) percentage level, fan speed in RPM,
potential noise level in centibels, and power in mA.
