No, we already have default rate and delay. Unless you can prove that
random firmware writer's idea of appropriate delay and rate is better
then current default - for everyone - and then can successfully argue
that that obviously best delay/rate combo should not replace the current
one but stay only in DT bindings, let's keep relying on users adjusting
their own preferences from respective desktop environments/console/etc.

Thanks.
