Previously, PNPACPI ignored these descriptors, so if a BIOS used them, a device could be responding at addresses the OS doesn't know about. This patch adds support for these descriptors in _CRS and _PRS. We don't attempt to encode them for _SRS (just like we don't attempt to encode the existing 16-, 32-, and 64-bit Address Space Descriptors). Unfortunately, I don't have a way to test this.
