	  Select this on platforms where the PMC device is discoverable
	  when scanning busses.

	  This should be disabled for devices running on battery since
	  it can draw much power. Further, it must be disabled, if S0ix
	  is enabled.

	  Disabling this option also stops the hardware TCO timer and makes
	  the TCO watchdog unavailable.
