Convert the *_orphan() device-creation calls in the hw/arm xlnx-versal, xlnx-zynqmp board files to the new parented API introduced earlier in this series, so every onboard device gets a stable path in the composition tree instead of landing in /machine/unattached with an unstable device[N] name.
The parent for each device is the object that owns its lifetime: the machine for board-created devices, the containing SoC device for composite children. Names follow existing QOM conventions.
