qom: Less verbose object_initialize_child()
All users of object_initialize_child() pass the obvious child size
argument. Almost all pass &error_abort and no properties. Tiresome.
Rename object_initialize_child() to
object_initialize_child_with_props() to free the name. New
convenience wrapper object_initialize_child() automates the size
argument, and passes &error_abort and no properties.
Rename object_initialize_childv() to
object_initialize_child_with_propsv() for consistency.
Convert callers with this Coccinelle script:
@@
expression parent, propname, type;
expression child, size;
symbol error_abort;

Note that Coccinelle chokes on ARMSSE typedef vs. macro in
hw/arm/armsse.c. Worked around by temporarily renaming the macro for
the spatch run.
