Paolo Bonzini fe04f0b4a1 hw/display/xlnx_dp: Move problematic code from instance_init to realize
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.

Markus Armbruster 121d07125b Clean up header guards that don't match their file name
Header guard symbols should match their file name to make guard
collisions less likely.  Offenders found with
scripts/clean-header-guards.pl -vn.

Cleaned up with scripts/clean-header-guards.pl, followed by some
renaming of new guard symbols picked by the script to better ones.

Peter Maydell e0dadc1e9e aux: Rename aux.[ch] to auxbus.[ch] for the benefit of Windows
On Windows 'aux.*' is a reserved name and cannot be used for
filenames; see
