While I don't know the policy for backporting major dts changes, I don't think 
backporting all the msm8974 cleanup to anything older is really worth it.

I also don't think there's actually a user of msm8974 stable, all the activity 
I know of happens on the latest mainline plus some extra patches on top for 
extra functionality that cannot be upstreamed yet.

Luca
