On the newer SoCs such as the H3 and A64 this is set by default to transfer a 0 after each sample in each slot. However the A10 and A20 SoCs that this driver was developed on had a default setting where it padded the audio gain with zeros.
This isn't a problem while we have only support for 16bit audio but with larger sample resolution rates in the pipeline then SEXT bits should be cleared so that they also pad at the LSB. Without this the audio gets distorted.
Set sign extend sample for all the sunxi generations even if they are not affected. This will keep coherency and avoid relying on default.
Isn't it coherence? But I guess consistency would be a better fit here.
