powerpc/eeh: Remove eeh information from pci_dn
The patch removes the eeh information from pci_dn since the eeh
device (struct eeh_dev) already contained those information and
the copy in pci_dn is no longer used except for the pseries iommu
mapping code, which we change to retrieve the PE address from eeh
device instead.
