[ALSA] hda-codec - Add workaround for multiple HPs
Dell laptops have multiple HP jacks that can be used for multi-channel
outputs. The current auto pincfg handles the speaker as the primary
output and thus cannot handle the multi-channel configuration for such
cases. This patch adds a workaround to fix this issue by swapping the
HP and speaker during multi-channel setup routines.
