PCI: Log all resource claims

Browse Source 
There are two ways to graft resource into resource tree in PCI,
pci_assign_resource() and pci_claim_resource(). Only the former logs
the action, which complicated troubleshooting the cases where resources
are assigned by pci_claim_resource(), which mostly assigns the addresses
inherited from the FW.

Add logging into pci_claim_resource() to make troubleshooting easier.
