If you don't want to use the controller device name to do the
matching, we can use the con_id string as well. I believe the lookup
method I use in this set just needs a small change.

Do you mean, leave it in the platform code? Why? We would reduce the
platform code by moving it to the mfd driver. Or did I misunderstood
something?
