This implements the fixed rate clocks generated either inside or

sclk_hdmiphy clock, which shall be later used by other drivers,
such as the DRM.

Since the external fixed rate clock fin_pll is now registered by
the clk-exynos5410 file, the bindings with the device tree file have
changed. It is no longer needed to define fin_pll as a fixed clock,
such as in:

	fin_pll: xxti {
  		compatible = "fixed-clock";
	  	clock-frequency = <24000000>;
	  	clock-output-names = "fin_pll";
	  	#clock-cells = <0>;
	};

The above lines should be replaced by the following lines:

	fixed-rate-clocks {
		oscclk {
			compatible = "samsung,exynos5410-oscclk";
			clock-frequency = <24000000>;
		};
	};

This new form of binding was properly documented in the relevant
documentation file.

Can you explain what is rationale behind this change ? Is it related to
suspend/resume ordering ?
Obviously it breaks the kernel/dtb compatibility. We should be moving
in opposite direction, i.e. completely remove the custom samsung fixed
rate clocks. I've tried to address this with patches [1], [2] but Tomasz
wasn't happy with them IIRC and I postponed work on that.
