O-Subject: [RHEL-7.5 qemu-kvm-ma PATCH 08/12] s390x/ipl: The s390-ipl device is not hot-pluggable
Bugzilla: 1492033

The s390-ipl device can not be created by the user, since it is meant only
to  be instantiated once internally to load the ROMs and kernel. If the user
tries to do a "device_add s390-ipl" via the monitor later, QEMU aborts with
a "ROM images must be loaded at startup" error message.
