The choice should be mutually exclusive. You either have ACPI manage the GPIOs via a PowerResource, or you have the OS driver manage the GPIOs. Having both results in the GPIOs being in an unknown state. I hope we can switch to using an enum to select the option down the road since having two bits is confusing and error prone.
