Workaround fixed I/O port resources encoded as I/O port ranges in _CRS.

ACPI I/O port descriptors use _MIN and _MAX fields to specify the set
of allowable base (start) addresses for an I/O port resource along with
a _LEN field specifying the length.  A fixed resource is supposed to be
encoded with _MIN == _MAX, but some buggy firmwares instead set _MAX to
the end of the fixed range.  Relocating I/O ranges only make sense in
_PRS (possible resource settings), not in _CRS (current resource settings),
so if an I/O port range with _MAX set set to the end of the range is
present in _CRS, treat it as a fixed I/O port resource starting at
_MIN.
