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/.

+* Uploaded QE firmware
+
+      If a new firmware has been uploaded to the QE (usually by the
+      boot loader), then a 'firmware' child node should be added to the QE
+      node.  This node provides information on the uploaded firmware that
+      device drivers may need.
+
+      Required properties:
+      - id: The string name of the firmware.  This is taken from the 'id'
+            member of the qe_firmware structure of the uploaded firmware.
+            Device drivers can search this string to determine if the
+            firmware they want is already present.
+      - extended-modes: The Extended Modes bitfield, taken from the
+		   firmware binary.  It is a 64-bit number represented
+		   as an array of two 32-bit numbers.
+      - virtual-traps: The virtual traps, taken from the firmware binary.
+		  It is an array of 8 32-bit numbers.
+
+Example:
+	firmware {
+		id = "Soft-UART";
+		extended-modes = <0 0>;
+		virtual-traps = <0 0 0 0 0 0 0 0>;
+	};
