commit 2302beb8c7b4389ee1bc034b0c3c14a7622dad02
Author: Duncan Laurie <dlaurie at chromium.org>

lynxpoint: Add ACPI Method to enable GPIO as wake source
This is an LPT-LP specific method that will enable a specific
GPIO as an ACPI SCI wake source.
It can be used by a device _DSW method to enable a pin that is
otherwise not configured to generate SCI at runtime.
It will set:
- GPIO owner to ACPI
- GPIO route to SCI
- GPIO config to GPIO, Input, Inverted
Also clean up and remove ACPI field definitions that are unused
and/or incorrect.
