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/.

+* palmas device tree bindings
+
+The TI palmas family current members :-
+twl6035 (palmas)
+twl6037 (palmas)
+tps65913 (palmas)
+tps65914 (palmas)
+tps659038
+
+Required properties:
+- compatible : Should be from the list
+  ti,twl6035
+  ti,twl6036
+  ti,twl6037
+  ti,tps65913
+  ti,tps65914
+  ti,tps80036
+  ti,tps659038
+and also the generic series names
+  ti,palmas
+- interrupt-controller : palmas has its own internal IRQs
+- #interrupt-cells : should be set to 2 for IRQ number and flags
+  The first cell is the IRQ number.
+  The second cell is the flags, encoded as the trigger masks from
+  Documentation/devicetree/bindings/interrupts.txt
+- interrupt-parent : The parent interrupt controller.
+
+Optional properties:
+  ti,mux-padX : set the pad register X (1-2) to the correct muxing for the
+		hardware, if not set will use muxing in OTP.
+
+Example:
+
+palmas {
+	compatible = "ti,twl6035", "ti,palmas";
+	reg = <0x48>
+	interrupt-parent = <&intc>;
+	interrupt-controller;
+	#interrupt-cells = <2>;
+
+	ti,mux-pad1 = <0>;
+	ti,mux-pad2 = <0>;
+
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	pmic {
+		compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
+		....
+	};
+}
