That is a possibility, but the idea is to reduce code in the platform 
area, not add to it. We'd also need a completely separate platform_data 
structure to the one we use for platform registration, as much of it has 
now been moved into Device Tree. The regulators are a good example of 
this, but there's also GPIO information which is no longer relevant etc.

I do believe that registering the AB8500 from the DB8500 is appropriate 
though, for the simple reason that the AB8500 is a sub-device to the 
DB8500. I think this is the correct thing to do. But anyway, as I said 
before, that ship has sailed. We _already_ do this. All this patch does 
is prevent the AB8500 from being registered twice when DT is not enabled.
