PNPACPI: add window support
Add support for resource windows. This is for bridge resources, i.e., regions where a bridge forwards transactions from the primary to the secondary side. This does not add support for *setting* windows via the /proc interface. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
