[PATCH 3/4] ASoC: fsl_sai: separate 'is_dsp_mode' for tx and rx

From: Shengjiu Wang
Date: Fri Mar 28 2025 - 05:00:15 EST


The transmitter and receiver of SAI can be used for different dsp modes,
then 'is_dsp_mode' needs to be separated.

Expand 'is_dsp_mode' to array 'is_dsp_mode[]' to support different
configuration of tx and rx.
