Allow non-fixed endpoints for a producer address range if the length of
the resource covers the entire range. Some BIOSes appear to mark
endpoints as non-fixed incorrectly (non-fixed endpoints are supposed to
be used in _PRS when OSPM is allowed to allocate a certain chunk of
address space within a larger range, I don't believe it is supposed to be
used for _CRS).
