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.
