Let's use the pci/platform-specialized functions for mapping a resource,
and pass the mapped address to intel_spi_probe. Benefits are:
- No separate call needed for getting the resource, and no access to
struct pci_dev internals (pdev->resource[]).
- More user-friendly output in /proc/iomem. In my case:
before
80704000-80704fff : 0000:00:1f.5
80704000-80704fff : 0000:00:1f.5 0000:00:1f.5
after
80704000-80704fff : 0000:00:1f.5
80704000-80704fff : spi_intel_pci
