s390x/sclp: mark sclp-cpu-hotplug as non-usercreatable
A TYPE_SCLP_CPU_HOTPLUG device for handling cpu hotplug events
is already created by the sclp event facility. Adding a second
TYPE_SCLP_CPU_HOTPLUG device via -device sclp-cpu-hotplug creates
an ambiguity in raise_irq_cpu_hotplug(), leading to a crash once
a cpu is hotplugged.
To fix this, disallow creating a sclp-cpu-hotplug device manually.
