hw/misc/macio: Mark the macio devices with user_creatable = false

Browse Source 
The macio devices currently cause a crash when the user tries to
instantiate them on a different machine:

$ ppc64-softmmu/qemu-system-ppc64 -device macio-newworld
Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:222:
qemu-system-ppc64: -device macio-newworld: Device 'serial0' is in use
Aborted (core dumped)

These devices are clearly not intended to be creatable by the user
since they are using serial_hds[] directly in their instance_init
function. So let's mark them with user_creatable = false.
