[PATCH 09/16] qemu: Assign PCI addresses for mediated devices as well

[Erik Skultety <eskultet@xxxxxxxxxx>]

So far, the official support is for x86_64 arch guests so unless a
different device API than vfio-pci is available let's assume PCI address
assignment. Once a different device API is introduced, we'll actually
have to start checking for the device API in the sysfs in order to
assign a correct type of address.
