Right.

It's not being removed, it's just not allowed to be upstreamed. Once we 
enforce Device Tree only booting, we'll go round and remove that 
capability from the drivers. Until then, you must ensure all Device Tree 
enablement works in parallel with platform registration.

Concentrate on enabling the drivers for DT for now and we'll extract 
platform data support later.
