From: Thomas Huth <thuth@redhat.com>

The device can not be instantiated by the user and QEMU currently
aborts when you try to use it:

$ x86_64-softmmu/qemu-system-x86_64 -device cpu-cluster
qemu-system-x86_64: hw/cpu/cluster.c:73: cpu_cluster_realize:
 Assertion `cbdata.cpu_count > 0' failed.
Aborted (core dumped)

Since this is an internal device only, mark it with user_creatable = false.
