This adds the necessary device tree changes to enable analog audio output on the PINE64 Quartz64 Model B with its RK809 codec. The headphone detection pin is left out for now because I couldn't get it to work and am not sure if it even matters, but for future reference: It's pin GPIO4 RK_PC4, named HP_DET_L_GPIO4_C4 in the schematic.
