superio/acpi/pnp_generic.asl: Add _PRS for each device
Simply return the current resource settings in the _PRS method. This
means that coreboot has to correctly set up the resources on the
device. This won't result in any regression as without _PRS the ACPI
OS would not know what resources settings are valid, so it would never
use _SRS.
