It would definitely be an improvement when all mapping would be done in
pci core. We could thus finally fix bridge filtering.
The hardest part with this change would be legacy vga class.
I am not so sure about adding an extra level of indirection
for all memory/io transactions. What we do now is perform
setup during bus scan, afterwards cpu calls device directly,
which looks nicer on the surface. Maybe we just need to
make callbacks more generic.
