There seems to be no limit to the amount of gunk the firmware can leave behind. Some platforms leave pch dplls on which are not in active use at all. The example in the bug report is a Apple Macbook Pro. Note that this escape scrunity of the hw state checker until we've tried to use this enabled, but unused pll since we did only check for the inverse case of a in-used, but disabled pll. v2: Add a WARN in the pll state checker which would have caught this case.
