PCI: Remove pcim_iomap_regions_request_all()

pcim_iomap_regions_request_all() have been deprecated in
commit e354bb8 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()").

All users of this function have been ported to other interfaces by now.

Remove pcim_iomap_regions_request_all().
