dt-bindings: clock: Convert i.MX6SLL clock to json-schema

* Clock bindings for Freescale i.MX6 SLL

Required properties:

- compatible: Should be "fsl,imx6sll-ccm"

- reg: Address and length of the register set

- #clock-cells: Should be <1>

- clocks: list of clock specifiers, must contain an entry for each required

  entry in clock-names

- clock-names: should include entries "ckil", "osc", "ipp_di0" and "ipp_di1"

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

ID in its "clocks" phandle cell.  See include/dt-bindings/clock/imx6sll-clock.h

for the full list of i.MX6 SLL clock IDs.

Examples:

#include <dt-bindings/clock/imx6sll-clock.h>

clks: clock-controller@20c4000 {

		compatible = "fsl,imx6sll-ccm";

		reg = <0x020c4000 0x4000>;

		interrupts = <GIC_SPI 87 IRQ_TYPE_LEVEL_HIGH>,

			     <GIC_SPI 88 IRQ_TYPE_LEVEL_HIGH>;

		#clock-cells = <1>;

		clocks = <&ckil>, <&osc>, <&ipp_di0>, <&ipp_di1>;

		clock-names = "ckil", "osc", "ipp_di0", "ipp_di1";

};

uart1: serial@2020000 {

		compatible = "fsl,imx6sl-uart", "fsl,imx6q-uart", "fsl,imx21-uart";

		reg = <0x02020000 0x4000>;

		interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&clks IMX6SLL_CLK_UART1_IPG>,

			 <&clks IMX6SLL_CLK_UART1_SERIAL>;

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