ast currently ioremaps two PCI BARs using pcim_iomap(). It does not
perform a request on the regions, however, which would make the driver a
bit more robust.
PCI now offers pcim_iomap_region(), a managed function which both
requests and ioremaps a BAR.
Replace pcim_iomap() with pcim_iomap_region().
