The sun8i-h3 introduces a lot of changes to the i2s block such as different register locations, extended clock division and more operational modes. As we have to consider the earlier implementation then these changes need to be isolated.
None of the new functionality has been implemented yet, the driver has just been expanded to allow it work on the H3 SoC.

I'm pretty sure this should be ((period - 1) << 8).
