Combine the ChipIdea USB binding into a single document to reduce
duplication and fragmentation. This marks use of the old PHY bindings as
deprecated. Future compatible bindings should use generic PHY binding.

Thanks, Rob. These are what I plan to do in future too.

The above property is only for fsl, we may need to differentiate
generic and vendor properties for reader.
