Commit Message

pcim_iomap_regions() and pcim_iomap_table() have been deprecated by the
PCI subsystem in commit e354bb84a4c1 ("PCI: Deprecate
pcim_iomap_table(), pcim_iomap_regions_request_all()").

Port dfl-pci.c to the successor, pcim_iomap_region().

Consistently, replace pcim_iounmap_regions() with pcim_iounmap_region().

Now this becomes an unneeded wrapper on pcim_ioremap_region(). Can we
kill this helper completely?
