New fsl device bindings file

Guys,

I'm sure you'll hate for doing this, but I've asked Kim to create a  
new Documentation/powerpc/fsl-device-tree-bindings.txt as part of his  
SEC patch.

I'm going to move all the Freescale SoC related bindings into this new  
file.  One of the aspects of the new file is we will NOT having an  
ordinal heading index.

Once I accept his new patch that add bindings to the new file.

thanks

- k
