ARM: dts: Correct audio input route & set mic bias for am335x-pepper Audio-in was incorrectly routed to Line In. It should be Mic3L as per schematic. Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works. I see voltage of 2.475v across GND and micbias. With these changes, I can record audio with a pair of proliferate TRRS earbuds.
