powerpc/eeh: Create eeh_dev from pci_dn instead of device_node

Browse Source 
The patch adds function traverse_pci_dn(), which is similar to
traverse_pci_devices() except it takes pci_dn, not device_node
as parameter. The pci_dev.c has been reworked to create eeh_dev
from pci_dn, instead of device_node.
