Subject: [PATCH 2/4] ASoC: dt-bindings: mediatek,mt8188-mt6359: Update DAI link node pattern

The associated machine driver is not dependent on the format of DAI link
node names. This means we are allowed to use more descriptive names
instead of indices without impacting functionality.

Update the binding to accept arbitrary DAI link names with a "-dai-link"
suffix. This is the common pattern used by the target (MT8188) and other
(MT8195, MT8186 etc.) MediaTek-based Chromebooks.
