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/.

+* Atmel HW cryptographic accelerators
+
+These are the HW cryptographic accelerators found on some Atmel products.
+
+* Advanced Encryption Standard (AES)
+
+Required properties:
+- compatible : Should be "atmel,at91sam9g46-aes".
+- reg: Should contain AES registers location and length.
+- interrupts: Should contain the IRQ line for the AES.
+- dmas: List of two DMA specifiers as described in
+        atmel-dma.txt and dma.txt files.
+- dma-names: Contains one identifier string for each DMA specifier
+             in the dmas property.
+
+Example:
+aes@f8038000 {
+	compatible = "atmel,at91sam9g46-aes";
+	reg = <0xf8038000 0x100>;
+	interrupts = <43 4 0>;
+	dmas = <&dma1 2 18>,
+	       <&dma1 2 19>;
+	dma-names = "tx", "rx";
+
+* Triple Data Encryption Standard (Triple DES)
+
+Required properties:
+- compatible : Should be "atmel,at91sam9g46-tdes".
+- reg: Should contain TDES registers location and length.
+- interrupts: Should contain the IRQ line for the TDES.
+
+Optional properties:
+- dmas: List of two DMA specifiers as described in
+        atmel-dma.txt and dma.txt files.
+- dma-names: Contains one identifier string for each DMA specifier
+             in the dmas property.
+
+Example:
+tdes@f803c000 {
+	compatible = "atmel,at91sam9g46-tdes";
+	reg = <0xf803c000 0x100>;
+	interrupts = <44 4 0>;
+	dmas = <&dma1 2 20>,
+	       <&dma1 2 21>;
+	dma-names = "tx", "rx";
+};
+
+* Secure Hash Algorithm (SHA)
+
+Required properties:
+- compatible : Should be "atmel,at91sam9g46-sha".
+- reg: Should contain SHA registers location and length.
+- interrupts: Should contain the IRQ line for the SHA.
+
+Optional properties:
+- dmas: One DMA specifiers as described in
+        atmel-dma.txt and dma.txt files.
+- dma-names: Contains one identifier string for each DMA specifier
+             in the dmas property. Only one "tx" string needed.
+
+Example:
+sha@f8034000 {
+	compatible = "atmel,at91sam9g46-sha";
+	reg = <0xf8034000 0x100>;
+	interrupts = <42 4 0>;
+	dmas = <&dma1 2 17>;
+	dma-names = "tx";
+};
