EDAC, fsl_ddr: Add support for little endian
Get endianness from device tree. Both big endian and little endian are supported. Default to big endian for backwards compatibility to MPC85xx.

+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@2000 {
+ compatible = "fsl,bsc9132-memory-controller";
+ reg = <0x2000 0x1000>;
+ interrupts = <16 2 1 8>;
+ };
+
+
+Example 2:
+
+ ddr1: memory-controller@8000 {
+ compatible = "fsl,qoriq-memory-controller-v4.7",
+ "fsl,qoriq-memory-controller";
+ reg = <0x8000 0x1000>;
+ interrupts = <16 2 1 23>;
+ };
