ARM: dts: sun8i: Add audio codec, dai and card for A33
Add the audio codec, dai and a simple card to be able to use the audio stream of the builtin codec on sun8i SoC. This commit adds also an audio-routing for the sound card node to link the analog DAPM widgets (Right/Left DAC) and the digital one's as they are created in different drivers.
