I hardly expected more OF_DECLARE macros when I opened this up. Given 
desires to get rid of them, I don't think adding to it is the way 
forward. That wrapping a platform driver around OF_DECLARE looks pretty 
horrible IMO. 

I browsed some of the discussion around this. It didn't seem like it's 
a large number of drivers that have to be fixed to defer probe 
correctly. Am I missing something?

I'd rather keep the pressure on getting fw_devlink on by default.
