ASoC: sun4i-i2s: Support for Allwinner R329 and D1 SoCs

Merge series from Samuel Holland <samuel@sholland.org>:

This series extends the sun4i-i2s binding and driver to support some
newer versions of the hardware. Each instance of the hardwar now has
multiple input/output pins, and channels can be muxed between them.
Since so far the driver only supports a "default" linear channel map,
the driver changes are minimal.
