This is the same transformation as in the previous commit, except
sysbus_init_child_obj() and realize are too separated for the commit's
Coccinelle script to handle, typically because sysbus_init_child_obj()
is in a device's instance_init() method, and the matching realize is
in its realize() method.
Perhaps a Coccinelle wizard could make it transform that pattern, but
I'm just a bungler, and the best I can do is transforming the two
separate parts separately:

This script is *unsound*: we need to manually verify init and realize
conversions are properly paired.
This commit has only the pairs where object_initialize_child()'s
@child and sysbus_realize()'s @dev argument text match exactly within
the same source file.
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.
