[PARISC] Fix infinite loop in /proc/iomem
pcibios_link_hba_resources() could corrupt the resource tree by inserting resources in the wrong place. Fix this by calling pci_claim_resource() for PCI-PCI bridges. Delete pcibios_link_hba_resources as we shouldn't need it any more. Also get rid of lba_claim_dev_resources() and just call pci_claim_resource() directly.
