[PATCH 12/17] ARM: dts: Add missing aess node and binding for omap4

On omap4 we're missing the aess node with it's related "ti,hwmods"
property that the SoC interconnect code needs.

Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.

+Texas Instruments Audio Engine Subsystem (AESS) binding
+
+AESS performs real-time signal processing on TI SoCs.
+
+
+Required properties:
+
+compatible: Shall be one of the following:
+ "ti,omap4-aess"
+
+reg: Shall contain the device instance IO range
+
+interrupts: Shall contain the device instance interrupt
+
+
+Optional properties:
+
+reg-names: Shall contain the IO range names if multiple IO
+ ranges are used by the SoC
+
+ti,hwmods: Shall contain the TI interconnect module name if needed
+ by the SoC
+
+
+Example:
+
+ aess: aess@401f1000 {
+ compatible = "ti,omap4-aess";
+ reg = <0x401f1000 0x400>, /* MPU private access */
+ <0x490f1000 0x400>; /* L3 Interconnect */
+ reg-names = "mpu", "dma";
+ ti,hwmods = "aess";
+ };
