armv7m: Make cpu object a child of the armv7m container

Rather than just creating the CPUs with object_new, make them child
objects of the armv7m container. This will allow the cluster code to
find the CPUs if an armv7m object is made a child of a cluster object.
object_new_with_props() will do the parenting for us.
