  In etdm dai driver, dai_etdm_parse_of() function is used to parse dts
properties to get parameters. There are two for-loops which are
sepearately for all etdm and etdm input only cases. In etdm in only
loop, dai_id is not initialized, so it keeps the value intiliazed in
another loop.

In the patch, add the missing initialization to fix the unexpected
parsing problem.

Fixes: 1de9a54acafb ("ASoC: mediatek: mt8195: support etdm in platform driver")
