Subject: [PATCH v1] ASoC: amd: acp: update tdm channels for specific DAI

From: Hemalatha Pinnamreddy <hemalatha.pinnamreddy2@....com>

TDM channel updates were applied to all DAIs, causing configurations
to overwrite for unrelated streams. The logic is modified to update
channels only for targeted DAI. This prevents corruption of other DAI
settings and resolves audio issues observed during system suspend and
resume cycles.
