Subject: [PATCH v2 3/3] ASoC: qcom: sc8280xp: Fix DAI format setting for MI2S interfaces

The current implementation does not configure the CPU DAI format for
MI2S interfaces, resulting in -EIO errors during audio playback and
capture. This prevents the correct clock from being enabled for the
MI2S interface. Configure the required DAI format to enable proper
clock settings. Tested on Lemans evk platform.
