spapr_pci: Fix DRC owner in spapr_dt_pci_bus()
spapr_dt_drc() scans the aliases of all DRConnector objects and filters
the ones that it will use to generate OF properties according to their
owner and type.
Passing bus->parent_dev _works_ if bus belongs to a PCI bridge, but it is
NULL if it is the PHB's root bus. This causes all allocated PCI DRCs to
be associated to all PHBs (visible in their "ibm,drc-types" properties).
As a consequence, hot unplugging a PHB results in PCI devices from the
other PHBs to be unplugged as well, and likely confuses the guest.
Use the same logic as in add_drcs() to ensure the correct owner is passed
to spapr_dt_drc().
