onyx_prepare() accepts 32/44.1/48 kHz PCM playback, but it leaves the Onyx IEC958 sample-rate status bits at the driver's initial 44.1 kHz setting in DIG_INFO3. As a result, 32 kHz and 48 kHz PCM streams advertise a stale IEC958 sample rate unless userspace rewrites IEC958 Playback Default first. Update only the consumer sample-frequency bits in DIG_INFO3 from the PCM runtime during prepare, resolving the long-standing FIXME in the PCM playback path while leaving the other user-controlled IEC958 status bits unchanged. Mark IEC958 Playback Default as volatile as well, since prepare() now changes the exposed register contents outside the control put callback.
