Roman Volkov 1f91ecc14d ALSA: oxygen: modify adjust_dg_dac_routing function
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.

*
* Playback:
* I²S 1 -> CS4245
* I²S 2 -> CS4361 (center/LFE)
* I²S 3 -> CS4361 (surround)
* I²S 4 -> CS4361 (front)
* Capture:
* I²S ADC 1 <- CS4245
*
* GPIO 3 <- ?
* GPIO 4 <- headphone detect
* GPIO 5 -> enable ADC analog circuit for the left channel
* GPIO 6 -> enable ADC analog circuit for the right channel
* GPIO 7 -> switch green rear output jack between CS4245 and and the first
* channel of CS4361 (mechanical relay)
* GPIO 8 -> enable output to speakers
*
* CS4245:
*
* input 0 <- mic
* input 1 <- aux
* input 2 <- front mic
* input 4 <- line
* DAC out -> headphones
