ASoC: codecs: lpass-wsa-macro: Fix speaker quality distortion
Commit bb4a0f497bc1 ("ASoC: codecs: lpass: Drop unused AIF_INVALID first DAI identifier") removed first entry in enum with DAI identifiers, because it looked unused. Turns out that there is a relation between DAI ID and "WSA RX0 Mux"-like kcontrols (which use "rx_mux_text" array). That "rx_mux_text" array used first three entries of DAI IDs enum, with value '0' being invalid. The value passed tp "WSA RX0 Mux"-like kcontrols was used as DAI ID and set to configure active channel count and mask, which are arrays indexed by DAI ID. After removal of first AIF_INVALID DAI identifier, this kcontrol was updating wrong entries in active channel count and mask arrays which was visible in reduced quality (distortions) during speaker playback on several boards like Lenovo T14s laptop and Qualcomm SM8550-based boards.
