Bjorn Helgaas 3162b6f0c5 PNPACPI: truncate _CRS windows with _LEN > _MAX - _MIN + 1
The ACPI spec (sec 6.4.3.5 in v4.0) requires that for Address Space Resource
Descriptors, _LEN <= _MAX - _MIN + 1 in all cases, but there are BIOSes that
violate this.  We experimentally determined that Windows truncates the
resource so it doesn't extend past _MAX, so let's do the same thing in
Linux.
