qemu: Prepare to cater for more general address assignment

Currently qemuDomainAssignPCIAddresses() is called to assign addresses
to PCI devices.

We need to do something similar for devices with spapr-vio addresses.
So create one place where address assignment will be done, that is
qemuDomainAssignAddresses().
