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";
+	};
