arm64: dts: rockchip: Add analog audio output on quartz64-b

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.
