6.8-stable review patch. If anyone has any objections, please let me know.

commit 2e93a29b48a017c777d4fcbfcc51aba4e6a90d38 upstream.
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.
