[PATCH] ppc64: Fix PCI flags when using OF device tree
My code to set up the PCI tree from the Open Firmware device tree was setting IORESOURCE_* flags on the resources for the devices, but not the PCI_BASE_ADDRESS_* flags. This meant that some drivers misbehaved, and /proc/pci showed the wrong types for the resources. This fixes it.
