This patch adds the following properties for Exynos4412 interconnect
bus nodes:
 - samsung,interconnect-parent: 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.

Changes for v5:
 - adjust to renamed exynos,interconnect-parent-node property,
 - add properties in common exynos4412.dtsi file rather than
   in Odroid specific odroid4412-odroid-common.dtsi.
