ASoC: sun4i-i2s: Add support for the R329/D1 variant
This adds a new set of quirks to set the right RX channel map. Since
that is the only change to the register layout, reuse the H6 regmap
config by extending its last register. R329 support is added by its
compatible string. D1 uses R329 as its fallback compatible, so no
additional code change is needed for it.
