Subject: [PATCH 5.10 256/717] ASoC: Intel: Boards: tgl_max98373: update TDM slot_width

From: Sathyanarayana Nujella <sathyanarayana.nujella@...el.com>

[ Upstream commit 0d7f2459ae926a964ab211aac413d72074131727 ]

Speaker amp's SSP bclk configuration was changed in the topology file to be
based on 12.288MHz and dai_ops->hw_params is based on s32le format.
But, the TDM slot size remained set to 24 bits.
This inconsistency created audible noises and needs to be corrected.
This patch updates TDM slot width to 32.

Fixes: bc7477fc2ab4 ("ASoC: Intel: Boards: tgl_max98373: Update TDM configuration in hw_params")
