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()"). In mtip32xx, these functions can easily be replaced by their respective successors, pcim_request_region() and pcim_iomap(). Moreover, the driver's calls to pcim_iounmap_regions() in probe()'s error path and in remove() are not necessary. Cleanup can be performed by PCI devres automatically. Replace pcim_iomap_regions() and pcim_iomap_table(). Remove the calls to pcim_iounmap_regions().
