[ Upstream commit ed3655729182a59b9bef1b564c6fc2dcbbbe954e ]
Upon adding a new device from a DT node, we scan its properties and its children's properties in order to create a consumer/supplier relationship between the device and the property provider.
That said, it's possible for some of the node's children to be disabled, which will create links that'll never be fulfilled.
To get around this, use the for_each_available_child_of_node() function instead of for_each_available_node() when iterating over the node's children.
