Subject: [PATCH v3 3/7] ARM: dts: sun8i: v3s: add analog codec and frontend to v3s dts

The Allwinner V3s and V3 SoCs feature an integrated analog audio codec.
Additionally both have an analog frontend with mixers and amplifiers for
the codec.
This commit adds both, the analog codec and its frontend to the V3s dtsi.
