[patch 2.5-bk] PCI 2/3: misc fixes

[Ivan Kokshaysky]

- Use PCI_BUS_NUM_RESOURCES instead on `4' in pci_find_parent_resource;
- clean up pci_claim_resource() and make it a bit more informative;
- pdev_sort_resources() must be __devinit, as it's called from
  pbus_assign_resources_sorted(), which is __devinit now.

Ivan.
