How does this look for marking the device as non-migratable? It adds a

I'm not thrilled with the name but the functionality is spot on. I lack the
creativity to offer a better name suggestion :-)

Hmmm, in working on this it seems that the memory (from
qemu_ram_map()) is still attached even when the device is removed
(which causes migration to fail because there is an unexpected
memory).
Is something like cpu_unregister_physical_memory()/qemu_ram_free() needed?
