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/.

+Allwinner SoCs High Speed Timer Controller
+
+Required properties:
+
+- compatible :	should be "allwinner,sun5i-a13-hstimer" or
+		"allwinner,sun7i-a20-hstimer"
+- reg : Specifies base physical address and size of the registers.
+- interrupts :	The interrupts of these timers (2 for the sun5i IP, 4 for the sun7i
+		one)
+- clocks: phandle to the source clock (usually the AHB clock)
+
+Example:
+
+timer@01c60000 {
+	compatible = "allwinner,sun7i-a20-hstimer";
+	reg = <0x01c60000 0x1000>;
+	interrupts = <0 51 1>,
+		     <0 52 1>,
+		     <0 53 1>,
+		     <0 54 1>;
+	clocks = <&ahb1_gates 19>;
+};
