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/.

+
+Required properties:

+- reg: Should contain SSC registers location and length
+- interrupts: Should contain SSC interrupt
+- clock-names: tuple listing input clock names.

+Optional properties:
+  - atmel,clk-from-rk-pin: bool property.
+     - When SSC works in slave mode, according to the hardware design, the

+Required properties:

+- compatible : mmio-sram

+- reg : SRAM iomem address range
+
+Reserving sram areas:
+---------------------
+
+Each child of the sram node specifies a region of reserved memory. Each

+reserved memory.
+
+Following the generic-names recommended practice, node names should
+reflect the purpose of the node. Unit address (@<address>) should be
+appended to the name.
+
+Required properties in the sram node:
+
+- #address-cells, #size-cells : should use the same values as the root node
+- ranges : standard definition, should translate from local addresses
+           within the sram to bus addresses
+
+Required properties in the area nodes:
+
+- reg : iomem address range, relative to the SRAM range
+
+Optional properties in the area nodes:
+
+- compatible : standard definition, should contain a vendor specific string
+               in the form <vendor>,[<device>-]<usage>
+
+Example:
