Convert the i.MX GPT binding to DT schema format using json-schema.
Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Changes since V2:
- in compatible properties, group all the ones with the same
fallback to a single 'items' list using enum for the first entry.

-Required properties:
-
-- compatible : should be one of following:
- for i.MX1:
- - "fsl,imx1-gpt";
- for i.MX21:
- - "fsl,imx21-gpt";
- for i.MX27:
- - "fsl,imx27-gpt", "fsl,imx21-gpt";
- for i.MX31:
- - "fsl,imx31-gpt";
- for i.MX25:
- - "fsl,imx25-gpt", "fsl,imx31-gpt";
- for i.MX50:
- - "fsl,imx50-gpt", "fsl,imx31-gpt";
- for i.MX51:
- - "fsl,imx51-gpt", "fsl,imx31-gpt";
- for i.MX53:
- - "fsl,imx53-gpt", "fsl,imx31-gpt";
- for i.MX6Q:
- - "fsl,imx6q-gpt", "fsl,imx31-gpt";
- for i.MX6DL:
- - "fsl,imx6dl-gpt";
- for i.MX6SL:
- - "fsl,imx6sl-gpt", "fsl,imx6dl-gpt";
- for i.MX6SX:
- - "fsl,imx6sx-gpt", "fsl,imx6dl-gpt";
-- reg : specifies base physical address and size of the registers.
-- interrupts : should be the gpt interrupt.
-- clocks : the clocks provided by the SoC to drive the timer, must contain
- an entry for each entry in clock-names.
-- clock-names : must include "ipg" entry first, then "per" entry.

-Example:
-
-gpt1: timer@10003000 {
- compatible = "fsl,imx27-gpt", "fsl,imx21-gpt";
- reg = <0x10003000 0x1000>;
- interrupts = <26>;
- clocks = <&clks IMX27_CLK_GPT1_IPG_GATE>,
- <&clks IMX27_CLK_PER1_GATE>;
- clock-names = "ipg", "per";
-};
