This patch adds two fields tp the Exynos4412 DTS:
  - parent: to declare connections between nodes that are not in a
    parent-child relation in devfreq;
  - #interconnect-cells: required by the interconnect framework.

Please note that #interconnect-cells is always zero and node IDs are not
hardcoded anywhere.
