pci: implement bridge filtering
Support bridge filtering on top of the memory
API as suggested by Avi Kivity:
Create a memory region for the bridge's address space. This region is
not directly added to system_memory or its descendants. Devices under
the bridge see this region as its pci_address_space(). The region is
as large as the entire address space - it does not take into account
any windows.
For each of the three windows (pref, non-pref, vga), create an alias
with the appropriate start and size. Map the alias into the bridge's
parent's pci_address_space(), as subregions.
