The Pinebook has a headphone jack tied to the HP headphone output of the SoC, and internal speakers connected to the LINEOUT of the SoC, through a standalone amplifier.
This commit enables I2S, digital and analog parts of audio codec on Pinebook, along with a device node for the external amplifier.
