PCI: Make pcim_iounmap_region() a public function
The function pcim_iounmap_regions() is problematic because it uses a
bitmask mechanism to release / iounmap multiple BARs at once. It, thus,
prevents getting rid of the problematic iomap table mechanism which was
deprecated in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()").
pcim_iounmap_region() does not have that problem. Make it public as the
successor of pcim_iounmap_regions().
