This is the architecture-specific code. Actually, from QEMU point of
view, this code just adds a virtual PCI bridge. For example, on x86 this
is done in a some other way, so they already have virtio-pci working.

Why only xen_arm? Couldn't this be a fairly generic device which can be
instantiated on x86 too, both for real and emulated Xen guests? And
riscv/ppc too?
