Wouldn't the compatible string select whether the hardware instance
supports IBI or not?

I'd imagine that each specific synthesis of the DW IP would imply
corresponding hardware settings, and so would warrant its own compatible
value.

Maybe one for the DT folks: would this work better as individual
properties? Is there a policy here?

Cheers,
