[PATCH v2] ASoC: tegra: Fix DSPK 16-bit playback

From: Sameer Pujar
Date: Tue Mar 26 2024 - 06:48:11 EST


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.

* moved common setting to S32_LE switch case.
