qemu: move PCI slot assignment for PIIX3, Q35 into a separate function

Browse Source 
In order to be able to test for fully reserved PCI buses, assignment of
PCI slots for integrated devices needs to be moved to a separate function.
This also might be a good preparation if we decide to add support for
other chipsets as well.
