powerpc/eeh: Remove unnecessary config_addr from eeh_dev
The eeh_dev struct hold a config space address of an associated node and the very same address is also stored in the pci_dn struct which is always present during the eeh_dev lifetime. This uses bus:devfn directly from pci_dn instead of cached and packed config_addr. Since config_addr is made from device's bus:dev.fn, there is no point in keeping it in the debugfs either so remove that too.
