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.

-CFI or JEDEC memory-mapped NOR flash, MTD-RAM (NVRAM...)
-
-Flash chips (Memory Technology Devices) are often used for solid state
-file systems on embedded devices.
-
- - compatible : should contain the specific model of mtd chip(s)
-   used, if known, followed by either "cfi-flash", "jedec-flash"
-   or "mtd-ram".
- - reg : Address range(s) of the mtd chip(s)
-   It's possible to (optionally) define multiple "reg" tuples so that
-   non-identical chips can be described in one node.
- - bank-width : Width (in bytes) of the bank.  Equal to the
-   device width times the number of interleaved chips.
- - device-width : (optional) Width of a single mtd chip.  If
-   omitted, assumed to be equal to 'bank-width'.
- - #address-cells, #size-cells : Must be present if the device has
-   sub-nodes representing partitions (see below).  In this case
-   both #address-cells and #size-cells must be equal to 1.
-
-For JEDEC compatible devices, the following additional properties
-are defined:
-
- - vendor-id : Contains the flash chip's vendor id (1 byte).
- - device-id : Contains the flash chip's device id (1 byte).
-
-In addition to the information on the mtd bank itself, the
-device tree may optionally contain additional information
-describing partitions of the address space.  This can be
-used on platforms which have strong conventions about which
-portions of a flash are used for what purposes, but which don't
-use an on-flash partition table such as RedBoot.
-
-Each partition is represented as a sub-node of the mtd device.
-Each node's name represents the name of the corresponding
-partition of the mtd device.
-
-Flash partitions
- - reg : The partition's offset and size within the mtd bank.
- - label : (optional) The label / name for this partition.
-   If omitted, the label is taken from the node name (excluding
-   the unit address).
- - read-only : (optional) This parameter, if present, is a hint to
-   Linux that this partition should only be mounted
-   read-only.  This is usually used for flash partitions
-   containing early-boot firmware images or data which should not
-   be clobbered.
-
-Example:
-
-	flash@ff000000 {
-		compatible = "amd,am29lv128ml", "cfi-flash";
-		reg = <ff000000 01000000>;
-		bank-width = <4>;
-		device-width = <1>;
-		#address-cells = <1>;
-		#size-cells = <1>;
-		fs@0 {
-			label = "fs";
-			reg = <0 f80000>;
-		};
-		firmware@f80000 {
-			label ="firmware";
-			reg = <f80000 80000>;
-			read-only;
-		};
-	};
-
-Here an example with multiple "reg" tuples:
-
-	flash@f0000000,0 {
-		#address-cells = <1>;
-		#size-cells = <1>;
-		compatible = "intel,PC48F4400P0VB", "cfi-flash";
-		reg = <0 0x00000000 0x02000000
-		       0 0x02000000 0x02000000>;
-		bank-width = <2>;
-		partition@0 {
-			label = "test-part1";
-			reg = <0 0x04000000>;
-		};
-	};
-
-An example using SRAM:
-
-	sram@2,0 {
-		compatible = "samsung,k6f1616u6a", "mtd-ram";
-		reg = <2 0 0x00200000>;
-		bank-width = <2>;
-	};
