armv7m: Forward idau property to CPU object

Browse source 
Create an "idau" property on the armv7m container object which
we can forward to the CPU object. Annoyingly, we can't use
object_property_add_alias() because the CPU object we want to
forward to doesn't exist until the armv7m container is realized.
