The semantic difference between the deprecated device_legacy_reset()
function and the newer device_cold_reset() function is that the new
function resets both the device itself and any qbuses it owns,
whereas the legacy function resets just the device itself and nothing
else.

In s390-pci-inst.c we use device_legacy_reset() to reset an
S390PCIBusDevice.  This device doesn't have any child qbuses, so the
functions do the same thing and we can stop using the deprecated one.
