powerpc/ibmebus: Fix further device reference leaks
commit 815a7141c4d1b11610dccb7fcbb38633759824f2 upstream.
Make sure to drop any reference taken by bus_find_device() when creating
devices during init and driver registration.
Fixes: 55347cc9962f ("[POWERPC] ibmebus: Add device creation and bus probing based on of_device")
