dt-bindings: clock: Convert i.MX1 clock to json-schema

* Clock bindings for Freescale i.MX1 CPUs

Required properties:

- compatible: Should be "fsl,imx1-ccm".

- reg: Address and length of the register set.

- #clock-cells: Should be <1>.

The clock consumer should specify the desired clock by having the clock

ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx1-clock.h

for the full list of i.MX1 clock IDs.

Examples:

	clks: ccm@21b000 {

		#clock-cells = <1>;

		compatible = "fsl,imx1-ccm";

		reg = <0x0021b000 0x1000>;

	};

	pwm: pwm@208000 {

		#pwm-cells = <2>;

		compatible = "fsl,imx1-pwm";

		reg = <0x00208000 0x1000>;

		interrupts = <34>;

		clocks = <&clks IMX1_CLK_DUMMY>, <&clks IMX1_CLK_PER1>;

		clock-names = "ipg", "per";

	};
