Using xlnx-zynqmp-pmu-soc on the command line causes QEMU to crash:

 ./qemu-system-microblazeel -M petalogix-ml605 -device xlnx-zynqmp-pmu-soc
 **
 ERROR:tcg/tcg.c:813:tcg_register_thread: assertion failed: (n < tcg_max_ctxs)
 Bail out!
 Aborted (core dumped)

Mark the device with "user_creatable = false" to avoid that this can happen.
