DSPK configuration is wrong for 16-bit playback and this happens because
the client config is always fixed at 24-bit in hw_params(). Fix this by
updating the client config to 16-bit for the respective playback.

Do we perhaps want to move the common cif_conf.client_bits assignment
into the S32_LE case now? It doesn't make much sense to have a common
assignment that's overridden for the S16_LE case and only kept for the
only other alternative (S32_LE).

Yes, it makes sense to do so. Will send v2. Thanks.
