[PATCH] thunderbolt: Replace deprecated PCI functions

[Philipp Stanner <pstanner@redhat.com>]

pcim_iomap_table() and pcim_request_regions() have been deprecated in
commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()") and commit d140f80f60358 ("PCI:
Deprecate pcim_iomap_regions() in favor of pcim_iomap_region()").

Replace these functions with pcim_iomap_region().
