[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.
