ASoC: dt-bindings: mediatek,mt8188-afe: correct clock name

The original clock names are different from the list in driver code.
Correct the mismatched binding names in the patch.

Because no mt8188 upstream dts exists, it doesn't affect the existing
dts file.

Fixes: 692d25b67e10 ("ASoC: dt-bindings: mediatek,mt8188-afe: add audio afe document")
