[Qemu-devel] [for-2.11 PATCH 17/26] spapr_pci: introduce drc_id property

[Greg Kurz]

With the addition of PHB hotplug, we have a static number of DRCs
that can be used to handle hotplug/unplug operations on our PHBs,
and need a consistent way to map PHBs to these connectors, and
assign a unique identifiers for the connectors.

This patch adds a drc_id property for that purpose.
