[PATCH v2 2/4] cpufreq: dt-bindings: add bindings for mtk-cpufreq driver

[pi-cheng.chen]

Add dt-binding for mtk-cpufreq driver so that the driver could get SoC specific
information (intermediate_clk for now) from device tree.

+Mediatek cpufreq driver
+-------------------
+
+Mediatek SoC cpufreq driver for CPU frequency scaling.
+
+Required properties:
+- compatible: "mediatek,mtk-cpufreq"
+- intermediate_clk: The intermediate clock source which CPUs will switch to
+during CPU frequency transition.
+
+Examples:
+--------
+	mtk-cpufreq {
+		compatible = "mediatek,mtk-cpufreq";
+		intermediate_clk = <&apmixedsys APMIXED_MAINPLL>;
+	};
