pci-assign: Remove
Legacy PCI device assignment has been removed from Linux in 4.12, and had been deprecated 2 years ago there. We can remove it from QEMU as well. The ROM loading code was shared with Xen PCI passthrough, so move it to hw/xen. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
