[RFC PATCH v2 08/11] arm: dts: exynos: Add parents and #interconnect-cells to Exynos4412

[Artur ÅwigoÅ]

From: Artur ÅwigoÅ <a.swigon@xxxxxxxxxxxxxxxxxxx>

This patch adds two fields to 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. The above-mentioned parent-child relation in devfreq
means that there is a shared power line ('devfreq' property). The 'parent'
property only signifies an interconnect connection.
