... here - where do you use these properties? Driver ignores them.
Wil add a check in driver.
AFAIR, these were only for sc7280 where we supported two variants for audio.
we can drop this property altogether, But having this flag will make
sure that the bindings are in a ready state to accommodate a new variant
of sc8280xp with dsp bypass.
