[PATCH] spi: Replace deprecated PCI functions

[Philipp Stanner <pstanner@xxxxxxxxxx>]

pcim_iomap_table() and pcim_request_regions() have been deprecated in
commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()").

Replace these functions with pcim_iomap_region().
