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/.

+Some properties contain an ordered list of 1 or more datum which are
+normally accessed by index. However, some devices will have multiple
+values which are more naturally accessed by name. Device nodes can
+include a supplemental property for assigning names to each of the list
+items. The names property consists of a list of strings in the same
+order as the data in the resource property.
+
+The following supplemental names properties are defined.
+
+Resource Property Supplemental Names Property
+----------------- ---------------------------
+reg reg-names
+clocks clock-names
+interrupts interrupt-names
+
+Usage:
+
+The -names property must be used in conjunction with the normal resource
+property. If not it will be ignored.
+
+Examples:
+
+l4-abe {
+ compatible = "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ ranges = <0 0 0x48000000 0x00001000>, /* MPU path */
+ <1 0 0x49000000 0x00001000>; /* L3 path */
+ mcasp {

+ reg = <0 0x10 0x10>, <0 0x20 0x10>,
