rS308269: Add support for Allwinner H3 audio codec.
Summary

This patch adds support for the H3 audio codec. Audio controller is mostly the same as A10/A20 except some registers are shuffled around. The mixer interfaces are completely different between SoCs, so separate a10_mixer_class and h3_mixer_class are implemented.

Test Plan

Needs to be tested on an A10 or A20 board.

Would it pay to add a mute method to the mixer interface?

I think I can get away with muting/unmuting in mixer_set but for now I wanted to follow the model used by the existing driver. Getting rid of this callback would be a good future enhancement though.
