ASoC: sun4i-codec: Add support for A31 Line Out playback
The A31 integrated codec has a second "Line Out" output which does not include an integrated amplifier in its path. This path does have a separate volume control. This patch adds support for the playback path from the DAC to the Line Out pins.
