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/.

+Chips&Media Coda multi-standard codec IP
+========================================
+
+Coda codec IPs are present in i.MX SoCs in various versions,
+called VPU (Video Processing Unit).
+
+Required properties:
+- compatible : should be "fsl,<chip>-src" for i.MX SoCs:
+  (a) "fsl,imx27-vpu" for CodaDx6 present in i.MX27
+  (b) "fsl,imx53-vpu" for CODA7541 present in i.MX53
+  (c) "fsl,imx6q-vpu" for CODA960 present in i.MX6q
+- reg: should be register base and length as documented in the
+  SoC reference manual
+- interrupts : Should contain the VPU interrupt. For CODA960,
+  a second interrupt is needed for the MJPEG unit.
+- clocks : Should contain the ahb and per clocks, in the order
+  determined by the clock-names property.
+- clock-names : Should be "ahb", "per"
+- iram : phandle pointing to the SRAM device node
+
+Example:
+
+vpu: vpu@63ff4000 {
+	compatible = "fsl,imx53-vpu";
+	reg = <0x63ff4000 0x1000>;
+	interrupts = <9>;
+	clocks = <&clks 63>, <&clks 63>;
+	clock-names = "ahb", "per";
+	iram = <&ocram>;
+};
