hw/arm: Mark the "fsl,imx31" device with user_creatable = false
QEMU currently crashes when the user tries to instantiate the fsl,imx31
device manually:
$ aarch64-softmmu/qemu-system-aarch64 -M kzm -device fsl,,imx31
**
ERROR:/home/thuth/devel/qemu/tcg/tcg.c:538:tcg_register_thread:
assertion failed: (n < max_cpus)
Aborted (core dumped)
The kzm board (which is the one that uses this CPU type) only supports
one CPU, and the realize function of the "fsl,imx31" device also uses
serial_hds[] directly, so this device clearly can not be instantiated
twice and thus we should mark it with user_creatable = false.
