Follow-up on the issues I was experiencing, it looks like they are fixed
by a new bios I got from MSI:
https://www.techpowerup.com/vgabios/188263/188263
With this bios my PCIe Bus Errors are gone and I don't need to specify
the rom file in the xml anymore.
Not sure if this is known to everyone, but I had some problems with the
atiflash tool under linux as it did not recognise my RX480. It seems
that this was because the RX480 rom's needs to be initialized before
atiflash can access it. So in my case I needed to start my Windows
virtual machine before atiflash recognised my card.
