[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.
