powerpc/pci: Trace more information from pci_dn
Originally, EEH probes on device_node or pci_dev and populates the
corresponding eeh_dev. In the subsequent patches, EEH will probes
on pci_dn and populates the corresponding eeh_dev. So we have to
cache some information in pci_dn, either from device_node or SRIOV
PF's enablement platform hook, to populate the eeh_dev properly.
The motivation to probe pci_dn, instead of device node or pci_dev,
to populate eeh_dev is SRIOV VFs are dynamically created and we
don't have the corresponding device nodes for them.
