PCI: Deprecate pcim_iomap_regions() in favor of pcim_iomap_region()
pcim_iomap_regions() is a complicated function that uses a bit mask to
determine the BARs the user wishes to request and ioremap. Almost all users
only ever set a single bit in that mask, making that mechanism
questionable.
pcim_iomap_region() is now available as a more simple replacement.
Make pcim_iomap_region() a public function.
Mark pcim_iomap_regions() as deprecated.
