Subject: [PATCH v8 5/6] gpio: Replace deprecated PCI functions

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()").

Replace those functions with calls to pcim_iomap_region().
