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.

-PPC440SPe DMA/XOR (DMA Controller and XOR Accelerator)
-
-Device nodes needed for operation of the ppc440spe-adma driver
-are specified hereby. These are I2O/DMA, DMA and XOR nodes
-for DMA engines and Memory Queue Module node. The latter is used
-by ADMA driver for configuration of RAID-6 H/W capabilities of
-the PPC440SPe. In addition to the nodes and properties described
-below, the ranges property of PLB node must specify ranges for
-DMA devices.
-
- i) The I2O node
-
- Required properties:
-
- - compatible		: "ibm,i2o-440spe";
- - reg			: <registers mapping>
- - dcr-reg		: <DCR registers range>
-
- Example:
-
-	I2O: i2o@400100000 {
-		compatible = "ibm,i2o-440spe";
-		reg = <0x00000004 0x00100000 0x100>;
-		dcr-reg = <0x060 0x020>;
-	};
-
-
- ii) The DMA node
-
- Required properties:
-
- - compatible		: "ibm,dma-440spe";
- - cell-index		: 1 cell, hardware index of the DMA engine
-			  (typically 0x0 and 0x1 for DMA0 and DMA1)
- - reg			: <registers mapping>
- - dcr-reg		: <DCR registers range>
- - interrupts		: <interrupt mapping for DMA0/1 interrupts sources:
-			   2 sources: DMAx CS FIFO Needs Service IRQ (on UIC0)
-			   and DMA Error IRQ (on UIC1). The latter is common
-			   for both DMA engines>.
- - interrupt-parent	: needed for interrupt mapping
-
- Example:
-
-	DMA0: dma0@400100100 {
-		compatible = "ibm,dma-440spe";
-		cell-index = <0>;
-		reg = <0x00000004 0x00100100 0x100>;
-		dcr-reg = <0x060 0x020>;
-		interrupt-parent = <&DMA0>;
-		interrupts = <0 1>;
-		#interrupt-cells = <1>;
-		#address-cells = <0>;
-		#size-cells = <0>;
-		interrupt-map = <
-			0 &UIC0 0x14 4
-			1 &UIC1 0x16 4>;
-	};
-
-
- iii) XOR Accelerator node
-
- Required properties:
-
- - compatible		: "amcc,xor-accelerator";
- - reg			: <registers mapping>
- - interrupts		: <interrupt mapping for XOR interrupt source>
- - interrupt-parent	: for interrupt mapping
-
- Example:
-
-	xor-accel@400200000 {
-		compatible = "amcc,xor-accelerator";
-		reg = <0x00000004 0x00200000 0x400>;
-		interrupt-parent = <&UIC1>;
-		interrupts = <0x1f 4>;
-	};
-
-
- iv) Memory Queue Module node
-
- Required properties:
-
- - compatible		: "ibm,mq-440spe";
- - dcr-reg		: <DCR registers range>
-
- Example:
-
-	MQ0: mq {
-		compatible = "ibm,mq-440spe";
-		dcr-reg = <0x040 0x020>;
-	};
-
