winbond/w83627dhg: Fix logical device power down in ACPI
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.
