The instance_init function of devices should always succeed to be able
to introspect the device. However, the instance_init function of the
"openprom" device can currently fail, for example like this:
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'openprom'}}" \
| sparc64-softmmu/qemu-system-sparc64 -M sun4v,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
RAMBlock "sun4u.prom" already registered, abort!
Aborted (core dumped)
This should not happen. Fix this problem by moving the affected code from
instance_init into a realize function instead.
