Thanks, that looks good now.

Another slight concern here is why we need this separate data for i2s -
maybe adding the write/read ops to struct dw_hdmi_audio_data would be
a better thing to do, which would then allow the AHB audio to drop
the .base argument in the future.
I'm not that bothered about this though. So...
