This adds support for devices that will be allocated to an instance
once and left in a reserved=total state. An external workflow can
put them back into allocatable state by dropping reserved back to
zero. Note this requires PCI-in-placement tracking for the affected
devices and it is only valid for type-PCI and type-PF devices.
