2013-07-03winbond/w83627dhg: Fix logical device power down in ACPINico Huber
The W83627DHG has some power managements bits to power down individual logical devices. These are called `* Power Down`. Counterintuitively and in contrast to `Immediate Power Down` (bit to power down the whole chip), these bits are set when the respective logical device is powered. Unfortunately, our ACPI code set them wrong which led to disabled devices after a S3 suspend/resume. Adding an option how to set the PM bits and setting them to zero for the W83627DHG, corrects it. Tested with kontron/ktqm77.

2013-06-11Start ACPI framework for PnP (super i/o) devicesNico Huber
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.
