Probably should, but some reason we haven't on other Inside Secure IP. 
Perhaps they are just simple enough from a DT perspective to get away 
without. Also, there may not be any SoC associated with some of these. 
If there is an SoC, then better to add a compatible to help avoid any 
future DT changes.
