ipq806x: ASoC: qcom: lpass-cpu: Fix fallback SD line index handling
This fixes device tree registration for 'qcom,lpass-cpu' as used by
qcom-ipq8064 SoCs, and allows speaker audio to function.

This patch has been submitted (and merged, for -next; likely v6.3)
upstream.

Subject: [PATCH] ASoC: qcom: lpass-cpu: Fix fallback SD line index handling
[[ Submitted upstream as:

Currently queued for -next (v6.3?) as:

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.
