pci_bridge: use parent bus's address space
The switch to the new memory API caused the following problem: The pci device may call pci_register_bar() to use PCI bus's address space. But we don't init PCI bus's address space if it is not bus 0. A crash was reported: http://lists.gnu.org/archive/html/qemu-devel/2011-08/msg02243.html More work will be needed to make bridge filtering work correctly with the memory API.
