Subject: [PATCH 1/3] dt-bindings: memory: fsl: convert DDR controller to dtschema
Convert Freescale/NXP DDR memory controller bindings to DT schema format
using json-schema.
Previous bindings were not listing all compatibles, so scan through
devicetree sources and drivers to get these.

-Freescale DDR memory controller
-
-Properties:
-
-- compatible : Should include "fsl,chip-memory-controller" where
- chip is the processor (bsc9132, mpc8572 etc.), or
- "fsl,qoriq-memory-controller".
-- reg : Address and size of DDR controller registers
-- interrupts : Error interrupt of DDR controller
-- little-endian : Specifies little-endian access to registers
- If omitted, big-endian will be used.
-
-Example 1:
-
- memory-controller@...0 {
- compatible = "fsl,bsc9132-memory-controller";
- reg = <0x2000 0x1000>;
- interrupts = <16 2 1 8>;
- };
-
-
-Example 2:
-
- ddr1: memory-controller@...0 {
- compatible = "fsl,qoriq-memory-controller-v4.7",
- "fsl,qoriq-memory-controller";
- reg = <0x8000 0x1000>;
- interrupts = <16 2 1 23>;
