Subject: [PATCH v3 02/10] ata: ahci: Replace deprecated PCI functions

pcim_iomap_regions_request_all() 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 these functions with their successors, pcim_iomap() and
pcim_request_all_regions().
