Addition of the Altera SDRAM EDAC bindings and device tree changes
v2: Changes to SoC EDAC source code.
v3: Fix typo in device tree documentation.
v4,v5: No changes - bump version for consistency.
v6: Assign ECC registers in SDRAM controller to EDAC

+Altera SOCFPGA SDRAM Error Detection & Correction [EDAC]
+
+Required properties:
+- compatible : should contain "altr,sdram-edac";
+- reg : should contain the ECC register range in sdram
+ controller (address and length).
+- interrupts : Should contain the SDRAM ECC IRQ in the
+ appropriate format for the IRQ controller.
+
+Example:
+ sdramedac@0 {
+ compatible = "altr,sdram-edac";
+ reg = <0xffc2502C 0x28>;
+ interrupts = <0 39 4>;
+ };
