We may need to keep our memory management alive after we have unloaded the physical pci device. For example, if we have exported an object via dmabuf, that will keep the device around but the pci device may be removed before the dmabuf itself is released, use of the pci hardware will be revoked, but the memory and object management needs to persist for the dmabuf.
