[PATCH 09/17] ARM: dts: Add missing iss node and binding for omap4

On omap4 we're missing the iss 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 Imaging Subsystem (ISS) binding
+
+ISS is used for cameras on Texas Instruments SoCs. Note that this
+binding is still missing the connections to the external devices
+modeled for the driver.
+
+Required properties:
+
+compatible: Shall be one of the following:
+ "ti,omap4-iss"
+
+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:
+
+ iss: iss@52000000 {
+ compatible = "ti,omap4-iss";
+ reg = <0x52000000 0x1000000>;
+ interrupts = <GIC_SPI 24 IRQ_TYPE_LEVEL_HIGH>;
+ ti,hwmods = "iss";
+ };
