Subject: s390x/s390-virtio-ccw: Reset PCI devices during subsystem reset

Include-If: %if 0%{?suse_version} == 1315
Git-commit: db08244a3a7ec312dfed3fd9b88e114281215458
References: bsc#1179726

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.
