hw/ppc/spapr_rtc: Mark the RTC device with user_creatable = false
QEMU currently aborts unexpectedly when a user tries to do something like this: $ qemu-system-ppc64 -nographic -S -nodefaults -monitor stdio QEMU 2.9.92 monitor - type 'help' for more information (qemu) device_add spapr-rtc,id=spapr-rtc (qemu) device_del spapr-rtc ** ERROR:qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl) Aborted (core dumped) The RTC device is not meant to be hot-pluggable - it's an internal device only and it even should not be possible to create it a second time with the "-device" parameter, so let's mark this with "user_creatable = false".
