hw/misc/macio: Fix crash when listing device properties of macio device 

The macio-newworld device can currently be used to abort QEMU unexpectedly:

$ ppc-softmmu/qemu-system-ppc -S -M ref405ep,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 11, "major": 2},
 "package": "build-all"}, "capabilities": []}}
{ 'execute': 'qmp_capabilities' }
{"return": {}}
{ 'execute': 'device-list-properties',
  'arguments': {'typename': 'macio-newworld'}}
Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:222:
Device 'serial0' is in use
Aborted (core dumped)

qdev properties should be set during realize(), not during instance_init(),
so move the related code there to fix this problem.
