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:

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.
