[PATCH for-8.0 1/9] hw/s390x/s390-pci-inst.c: Use device_cold_reset() to

From: Peter Maydell
Subject: [PATCH for-8.0 1/9] hw/s390x/s390-pci-inst.c: Use device_cold_reset() to reset PCI devices
Date: Fri, 4 Nov 2022 16:15:05 +0000

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

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.
