PNPACPI complained about and ignored devices with ADDRESS16, ADDRESS32, or
ADDRESS64 descriptors in _PRS. HP firmware uses them for built-in serial
ports, so this patch adds support for parsing these descriptors from _PRS.
Note that this does not add the corresponding support for encoding them in
preparation for _SRS, because I don't have any machine that supports _SRS
on these descriptors, so I couldn't test that support. Attempts to encode
them will cause a warning and an -EINVAL return.
