Hmm, it should be safe to move it there. By specifying this property or not
we can control whether the I2S clocks are exposed or not. If we move it to 
exynos5250.dtsi the clocks we always be exposed. But should be the right thing
to do anyway. I will post v3.

Of course we recently made the clock-output-names property deprecated, it will
not bee needed any more. It was there just to ensure the clk names are unique.
