Subject: [RFC PATCH 01/34] ASoC: dt-bindings: Add a separate compatible for the A64 codec

The digital codec in the A64 is largely compatible with the one in the
A33, with two changes:
 - It is missing some muxing options for AIF1/2/3 (not currently
   supported by the driver)
 - It does not have the LRCK inversion issue that A33 has

To fix the Left/Right channel inversion on the A64 caused by the A33
LRCK fix, we need to introduce a new compatible for the codec in the
A64.

Fixes: ec4a95409d5c ("arm64: dts: allwinner: a64: add nodes necessary for analog sound support")
