ALSA: hda: cs35l41: Set Channel Index correctly when system is missing _DSD
Current method to set Channel Index when the system is missing _DSD
assumes that the channels alternate, which is not guaranteed.
Instead use the same methodology as the main driver does when _DSD
exists.
Fixes: 8c4c216db8fb ("ALSA: hda: cs35l41: Add config table to support many laptops without _DSD")
