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

Changes since V1:
- add the compatible strings per SoC;
- use "reset-controller" as node name instead of src;
- add interrupt items description.

-Freescale i.MX System Reset Controller
-======================================
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.
-
-Required properties:
-- compatible: Should be "fsl,<chip>-src"
-- reg: should be register base and length as documented in the
- datasheet
-- interrupts: Should contain SRC interrupt and CPU WDOG interrupt,
- in this order.
-- #reset-cells: 1, see below
-
-example:
-
-src: src@20d8000 {
- compatible = "fsl,imx6q-src";
- reg = <0x020d8000 0x4000>;
- interrupts = <0 91 0x04 0 96 0x04>;
- #reset-cells = <1>;
-};
-
-Specifying reset lines connected to IP modules
-==============================================
-
-The system reset controller can be used to reset the GPU, VPU,
-IPU, and OpenVG IP modules on i.MX5 and i.MX6 ICs. Those device
-nodes should specify the reset line on the SRC in their resets
-property, containing a phandle to the SRC device node and a
-RESET_INDEX specifying which module to reset, as described in
-reset.txt
-
-example:
-
- ipu1: ipu@2400000 {
- resets = <&src 2>;
- };
- ipu2: ipu@2800000 {
- resets = <&src 4>;
- };
-
-The following RESET_INDEX values are valid for i.MX5:
-GPU_RESET 0
-VPU_RESET 1
-IPU1_RESET 2
-OPEN_VG_RESET 3
-The following additional RESET_INDEX value is valid for i.MX6:
-IPU2_RESET 4
