Subject: [PATCH 4/9] block: mtip32xx: 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()").

In mtip32xx, these functions can easily be replaced by their respective
successors, pcim_request_region() and pcim_iomap(). Moreover, the
driver's call to pcim_iounmap_regions() is not necessary, because it's
invoked in the remove() function. Cleanup can, hence, be performed by
PCI devres automatically.

Replace pcim_iomap_regions() and pcim_iomap_table().

Remove the call to pcim_iounmap_regions().
