google/slippy: consolidate variants' common mainboard.asl code

Move code common code from each variant's mainboard.asl into
common ACPI code for all variants (like google/auron).  This also
adds the _PRW method for the LID0 device for falco and peppy, which
omitted the function  when they were originally upstreamed.

See Chromium commit c8b41f7, falco: Add _PRW for LID0 ACPI Device
