DR connector is a device that emulates a firmware abstraction used by PAPR
compliant guests to manage hotplug/dynamic-reconfiguration of PHBs, PCI
devices, memory, and CPUs.

It is internally created by the spapr platform and requires to be owned by
either the machine (PHBs, CPUs, memory) or by a PHB (PCI devices).
