Add devicetree binding for I2C devices and add bindings for optional parameters in the function drivers. Parameters for function drivers are defined in child nodes for each of the functions.

Sorry, but I told you the wrong suffix. It should be just '-ms'. I've finally done my TODO list item of documenting what suffixes to use. Otherwise, for the bindings: Acked-by: Rob Herring <robh@kernel.org>
