Subject: [PATCH 22/29] hw/ppc/spapr_pci.c: Use device_cold_reset() rather than
 device_legacy_reset()

In spapr_phb_children_reset() we call device_legacy_reset() to reset any
QOM children of the SPAPR PCI host bridge device. This will not reset
any qbus such a child might own. Switch to device_cold_reset(), which will
reset both the device and its buses. (If the child has no qbuses then
there will be no change in behaviour.)
