Is it possible to always set this bit and then have an override flag used in sdm845 that says to _not_ set this bit? Presumably on earlier platforms writing the bit is a no-op so it's safe to write the bit on those platforms. This way, if it's going to be the default we can avoid setting the flag and only set the flag on older platforms where it shouldn't be done for some reason.
Not all the subsystem clock controllers might have this hardware control bit set from design. Thus we want to set them based on the flag.
