Add devicetree source files as of Linux-3.15-rc2

This adds the Linux dts files to barebox. The dts files are
generated from Ian Campbells device-tree-rebasing.git:

git://xenbits.xen.org/people/ianc/device-tree-rebasing.git

The dts are found in dts/ in the barebox repository and
will be updated from upstream regularly, probably for each upstream
-rc.

To keep the synchronization with upstream easy no changes to
the original files are allowed under dts/. Instead changes to
upstream dts files will be done using overlays in arch/$ARCH/dts/.

+Required properties:
+- compatible: "ti,omap4-dmic"
+- reg: Register location and size as an array:
+       <MPU access base address, size>,
+       <L3 interconnect address, size>;
+- interrupts: Interrupt number for DMIC
+- interrupt-parent: The parent interrupt controller
+- ti,hwmods: Name of the hwmod associated with OMAP dmic IP
