Subject: [PATCH] dt-bindings: sound: sun8i-a33-codec: Add Allwinner A64 codec compatible fallback

make dtbs_check report a warning because the documentation
for the A64 codec compatible is missing.

The A64 codec compatible is actually a simple fallback to the A33.

Reflect this in the dt-bindings Documentation.
