This patch adds the following properties to the Exynos4412 DT:
- exynos,interconnect-parent-node: to declare connections between
nodes in order to guarantee PM QoS requirements between nodes;
- #interconnect-cells: required by the interconnect framework.
Note that #interconnect-cells is always zero and node IDs are not
hardcoded anywhere.
