> Macro for_each_child_of_node() makes it easy to iterate over all of the
> children for a given device tree node, including those nodes that are
> marked as unavailable (i.e. status = "disabled").
> 
> Introduce for_each_available_child_of_node(), which is like
> for_each_child_of_node(), but it automatically skips unavailable nodes.
> This also requires the introduction of helper function
> of_get_next_available_child(), which returns the next available child
> node.
