commit 000bca8d706d1bf7cca01af75787247c5a2fdedf upstream.
These indices should reference the ID placed within the dai_driver array, not the indices of the array itself.
This fixes commit 4ff028f6c108 ("ASoC: qcom: lpass-cpu: Make I2S SD lines configurable"), which among others, broke IPQ8064 audio (sound/soc/qcom/lpass-ipq806x.c) because it uses ID 4 but we'd stop initializing the mi2s_playback_sd_mode and mi2s_capture_sd_mode arrays at ID 0.
