I've not seen the specific example (though fankly it seems quite
surprising that there's anything other than bus speed that the platform
might want to configure for I2C...).

Well, if checking the DT checky box is the important thing then just
adding an of_match_table ought to be enough?  It's fairly common for
platform data to have lots of stuff that's not used by most systems
so you can often cover 90% of systems with a very small subset of the 
configurability.
