It is certainly optional, I added the property to solve some obscure
problems with probing, but I've noticed people using it more broadly.
I suspect it also speeds up booting a tiny bit.

DT is complex enough already, don't include useless compatible strings
in mainline - people will see and tend to blindly copy. Ideally your
vendor tree would use the standard property :|
