When I am laying out the dts, leaving out what isn't used makes the dts 
file cleaner, at least in my view. It doesn't hurt to have the second 
i2c bus there, but it also doesn't help and leaving it out points out 
that it is not used.

When we get a macro system I assume the second i2c bus will be there but 
hidden by a macro. It will still be clean and shouldn't cause grief.
