To support PHB hotplug we need to clean up lingering references, memory, child properties, etc. prior to the PHB object being finalized. Generally this will be called as a result of calling object_unparent() on the PHB object, which in turn would normally be called as the result of an unplug() operation. When the PHB is finalized, child objects will be unparented in turn, and finalized if the PHB was the only reference holder. so we don't bother to explicitly unparent child objects of the PHB, with the notable exception of DRCs. This is needed to avoid a QEMU crash when unplugging a PHB and resetting the machine before the guest could handle the event. The DRCs are removed from the QOM tree by pci_unregister_root_bus() and we must make sure we're not leaving stale aliases under the global /dr-connector path. The formula that gives the number of DMA windows is moved to an inline function in the hw/pci-host/spapr.h header because it will have other users. The unrealize function is able to cope with partially realized PHBs. It is hence used to implement proper rollback on the realize error path.
