[PATCH] powerpc: properly configure DDR/P5IOC children devs
The dynamic add path for PCI Host Bridges can fail to configure children
adapters under P5IOC controllers. It fails to properly fixup bus/device
resources, and it fails to properly enable EEH. Both of these steps
need to occur before any children devices are enabled in
pci_bus_add_devices().
