ARM: dts: exynos: Add interconnect properties to Exynos4412 bus nodes
This patch adds the following properties for Exynos4412 interconnect
bus nodes:
- interconnects: to declare connections between nodes in order to
guarantee PM QoS requirements between nodes,
- #interconnect-cells: required by the interconnect framework,
- samsung,data-clk-ratio: which allows to specify minimum data clock
frequency corresponding to requested bandwidth for each bus.
Note that #interconnect-cells is always zero and node IDs are not
hardcoded anywhere.
