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.

=== Host Device Assignment ===



QEMU supports assigning host PCI devices (qemu-kvm only at this time)

and host USB devices.

and host USB devices.  PCI devices can only be assigned with -device:



The old way to assign a host PCI device is



    -pcidevice host=ADDR,dma=none,id=ID



The new way is



    -device pci-assign,host=ADDR,iommu=IOMMU,id=ID



The old dma=none becomes iommu=off with -device.

    -device vfio-pci,host=ADDR,id=ID



The old way to assign a host USB device is
