Revert the guts of rev 1.14. This ends up attempting to turn of power

Revert the guts of rev 1.14.  This ends up attempting to turn of power
resources for devices that aren't present.  And that makes us run AML that
clearly hasn't been tested by the vendors.  And on my test laptop this no
longer seems to make a meaningful difference in the power consumption
during suspend-to-idle.
