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.

-PHY nodes
-
-Required properties:
-
- - device_type : Should be "ethernet-phy"
- - interrupts : <a b> where a is the interrupt number and b is a
-   field that represents an encoding of the sense and level
-   information for the interrupt.  This should be encoded based on
-   the information in section 2) depending on the type of interrupt
-   controller you have.
- - interrupt-parent : the phandle for the interrupt controller that
-   services interrupts for this device.
- - reg : The ID number for the phy, usually a small integer
- - linux,phandle :  phandle for this node; likely referenced by an
-   ethernet controller node.
-
-Example:
-
-ethernet-phy@0 {
-	linux,phandle = <2452000>
-	interrupt-parent = <40000>;
-	interrupts = <35 1>;
-	reg = <0>;
-	device_type = "ethernet-phy";
-};
