dt: Move device tree documentation out of powerpc directory
The device tree is used by more than just PowerPC. Make the documentation directory available to all. v2: reorganized files while moving to create arch and driver specific directories. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

+* Freescale 8xxx/3.0 Gb/s SATA nodes
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+Each SATA port should have its own node.
+
+Required properties:
+- compatible : compatible list, contains 2 entries, first is
+ "fsl,CHIP-sata", where CHIP is the processor
+ (mpc8315, mpc8379, etc.) and the second is
+ "fsl,pq-sata"
+- interrupts : <interrupt mapping for SATA IRQ>
+- cell-index : controller index.
+ 1 for controller @ 0x18000
+ 2 for controller @ 0x19000
+ 3 for controller @ 0x1a000
+ 4 for controller @ 0x1b000
+
+Optional properties:
+- interrupt-parent : optional, if needed for interrupt mapping
+- reg : <registers mapping>
+
+Example:
+ sata@18000 {
+ compatible = "fsl,mpc8379-sata", "fsl,pq-sata";
+ reg = <0x18000 0x1000>;
+ cell-index = <1>;
+ interrupts = <2c 8>;
+ interrupt-parent = < &ipic >;
+ };
