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/.

+OMAP HS USB Host TLL (Transceiver-Less Interface)
+
+Required properties:
+
+- compatible : should be "ti,usbhs-tll"
+- reg : should contain one register range i.e. start and length
+- interrupts : should contain the TLL module's interrupt
+- ti,hwmod : must contain "usb_tll_hs"
+
+Optional properties:
+
+- clocks: a list of phandles and clock-specifier pairs, one for each entry in
+  clock-names.
+
+- clock-names: should include:
+  * "usb_tll_hs_usb_ch0_clk" - USB TLL channel 0 clock
+  * "usb_tll_hs_usb_ch1_clk" - USB TLL channel 1 clock
+  * "usb_tll_hs_usb_ch2_clk" - USB TLL channel 2 clock
+
+Example:
+
+	usbhstll: usbhstll@4a062000 {
+		compatible = "ti,usbhs-tll";
+		reg = <0x4a062000 0x1000>;
+		interrupts = <78>;
+		ti,hwmods = "usb_tll_hs";
+	  };
