-Device-tree bindings for FSI-attached I2C master and busses

-Required properties:

- - reg = < address size >;		: The FSI CFAM address and address
-					  space size.
- - #address-cells = <1>;		: Number of address cells in child

- - #size-cells = <0>;			: Number of size cells in child nodes.
- - child nodes				: Nodes to describe busses off the I2C

-Child node required properties:
- - reg = < port number >		: The port number on the I2C master.
