PCI: pci-stub module to reserve pci device
When doing device assignment with KVM there's currently nothing to
protect the device from having a driver in the host as well as the guest.
This trivial module just binds the pci device on the host to a stub
driver so that a real host driver can't bind to the device. It has no
pci id table, it supports only dynamic ids.
