ALSA: oxygen: modify adjust_dg_dac_routing function

commit 1f91ecc14deea9461aca93273d78871ec4d98fcd upstream.

When selecting the audio output destinations (headphones,
FP headphones, multichannel output), the channel routing
should be changed depending on what destination selected.
Also unnecessary I2S channels are digitally muted. This
function called when the user selects the destination
in the ALSA mixer.
