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.

-Nintendo GameCube device tree
-=============================
-
-1) The "flipper" node
-
-  This node represents the multi-function "Flipper" chip, which packages
-  many of the devices found in the Nintendo GameCube.
-
-  Required properties:
-
-   - compatible : Should be "nintendo,flipper"
-
-1.a) The Video Interface (VI) node
-
-  Represents the interface between the graphics processor and a external
-  video encoder.
-
-  Required properties:
-
-   - compatible : should be "nintendo,flipper-vi"
-   - reg : should contain the VI registers location and length
-   - interrupts : should contain the VI interrupt
-
-1.b) The Processor Interface (PI) node
-
-  Represents the data and control interface between the main processor
-  and graphics and audio processor.
-
-  Required properties:
-
-  - compatible : should be "nintendo,flipper-pi"
-  - reg : should contain the PI registers location and length
-
-1.b.i) The "Flipper" interrupt controller node
-
-  Represents the interrupt controller within the "Flipper" chip.
-  The node for the "Flipper" interrupt controller must be placed under
-  the PI node.
-
-  Required properties:
-
-  - compatible : should be "nintendo,flipper-pic"
-
-1.c) The Digital Signal Procesor (DSP) node
-
-  Represents the digital signal processor interface, designed to offload
-  audio related tasks.
-
-  Required properties:
-
-   - compatible : should be "nintendo,flipper-dsp"
-   - reg : should contain the DSP registers location and length
-   - interrupts : should contain the DSP interrupt
-
-1.c.i) The Auxiliary RAM (ARAM) node
-
-  Represents the non cpu-addressable ram designed mainly to store audio
-  related information.
-  The ARAM node must be placed under the DSP node.
-
-  Required properties:
-
-   - compatible : should be "nintendo,flipper-aram"
-   - reg : should contain the ARAM start (zero-based) and length
-
-1.d) The Disk Interface (DI) node
-
-  Represents the interface used to communicate with mass storage devices.
-
-  Required properties:
-
-   - compatible : should be "nintendo,flipper-di"
-   - reg : should contain the DI registers location and length
-   - interrupts : should contain the DI interrupt
-
-1.e) The Audio Interface (AI) node
-
-  Represents the interface to the external 16-bit stereo digital-to-analog
-  converter.
-
-  Required properties:
-
-   - compatible : should be "nintendo,flipper-ai"
-   - reg : should contain the AI registers location and length
-   - interrupts : should contain the AI interrupt
-
-1.f) The Serial Interface (SI) node
-
-  Represents the interface to the four single bit serial interfaces.
-  The SI is a proprietary serial interface used normally to control gamepads.
-  It's NOT a RS232-type interface.
-
-  Required properties:
-
-   - compatible : should be "nintendo,flipper-si"
-   - reg : should contain the SI registers location and length
-   - interrupts : should contain the SI interrupt
-
-1.g) The External Interface (EXI) node
-
-  Represents the multi-channel SPI-like interface.
-
-  Required properties:
-
-   - compatible : should be "nintendo,flipper-exi"
-   - reg : should contain the EXI registers location and length
-   - interrupts : should contain the EXI interrupt
-
