PCI: Introduce pci_dev_for_each_resource()
Instead of open-coding it everywhere introduce a tiny helper that can be
used to iterate over each resource of a PCI device, and convert the most
obvious users into it.
While at it drop doubled empty line before pdev_sort_resources().
No functional changes intended.
