The TLV320AIC3x driver is currently the only user of the CODEC hw_read operation and is jumping through some hoops in order to do so. In order to support future refactoring to make the hw_read operation more usable unwrap the usage in this driver to avoid its use.

I don't have any hardware I can test this on so it'd be good if someone with suitable hardware could give it a spin. Daniel, you wrote the code that does the readbacks so I guess you're most likely to have a good test setup for this?
