s390x/s390-virtio-ccw: Reset PCI devices during subsystem reset
Currently, a subsystem reset event leaves PCI devices enabled, causing
issues post-reset in the guest (an example would be after a kexec). These
devices need to be reset during a subsystem reset, allowing them to be
properly re-enabled afterwards. Add the S390 PCI host bridge to the list
of qdevs to be reset during subsystem reset.
