What's the intention in doing this? What does it change?
We want to remove access to pre-QOM and possibly hotplug QOM paths
from external API (CLI & QMP so far).
When the parent object is obvious and missing we simply have to
explicit it.
It seems to be OK to pass a non-Device owner in for
memory_region_init() (whereas it is *not* OK to do that
for memory_region_init_ram()), but this seems to be
getting a bit tricky.
Yes, memory_region_init_ram() is problematic; I'm hardly trying
to ignore it at this point.
