[PATCH 7/9] net: dsa: hellcreek: Use of_find_node_by_name_balanced() to find device_node

[Zhang Zekun]

Instead of directly using of_node_get() before of_find_node_by_name()
to balance the refcount of the device_node, using wraper function
of_find_node_by_name_balanced() to make code logic a bit simplier.
