Start ACPI framework for PnP (super i/o) devices
I'm trying to make writing ACPI code for super i/o devices more
comfortable.
pnp.asl hosts some general cpp macros.
The other four files are to be included in dsdt trees. They are
controlled by cpp macros which should be defined/undefined before
inclusion.
Work was inspired by Christoph Grenz' ACPI code for the W83627HF.
