aux_create_slave() calls qdev_init_nofail() which in turn "realizes"
the corresponding object. This is unlike qdev_create(), and it is wrong
because qdev_init_nofail() must not be called from an instance_init
function. Move qdev_init_nofail() and the subsequent aux_map_slave into
the caller's realize function.
There are two more bugs that needs to be fixed here, too, where the
objects are created but not added as children. Therefore when
you call object_unparent on them, nothing happens.
In particular dpcd and edid give you an infinite loop in bus_unparent,
because device_unparent is not called and does not remove them from
the list of devices on the bus.

The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'. Although our coding style frowns on brace-less 'if':
if (cond)
statement;
else
something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'. But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'. Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.
The change should have no semantic impact. I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.
Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\

This device is private and is created once per aux-bus.
So don't allow the user to create one from command-line.
