ARM: sun7i: dt: Enable audio codec on pcDuino V3 Nano

The pcDuino V3 Nano has a 3.5mm TRRS jack socket for audio, using the CTIA standard pinout, connected to HPOUTL, HPOUTR, HPCOM/HPCOMFB and MICIN1/VMIC (via appropriate RC networks) on the A20. The PH00 GPIO is wired for headphone plug detection: it reads 0 when nothing's plugged in, and 1 when a plug is inserted.

LINEINL/R and FMINL/R are not connected.

Hi,

Ah, so there's a design out there with headphone detect. Cool :)

Do you feel like writing the headphone detection code?

Anyway, queued for 4.5, thanks!
