hw/arm/digic: Mark device with user_creatable = false
QEMU currently shows some unexpected behavior when the user trys to do a "device_add digic" on an unrelated ARM machine like integratorcp in "-nographic" mode (the device_add command does not immediately return to the monitor prompt), and trying to "device_del" the device later results in a "qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl)" error condition. Looking at the realize function of the device, it uses serial_hds directly and this means that the device can not be added a second time, so let's simply mark it with "user_creatable = false" now.
