Convert the *_orphan() device-creation calls in hw/i386 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 device for composite children. Names follow existing QOM conventions. Six of the singletons in hw/i386/kvm/ (kvmclock, xen-evtchn, xen-gnttab, xen-overlay, xen-xenstore, xen-primary-console) are created via a public helper; those helpers gain an Object *parent first argument and all callers are updated in this patch. The pcspk device created in pc_machine_initfn() is left orphan for now: it is created in instance_init and object_unref()ed in instance_finalize when never realized. Making it a child<> would free it via object_property_del_all() before finalize runs, leaving finalize with a dangling pointer. This site needs a separate refactor of pc_machine_finalize() first.
