ASoC: Remove use of hw_read from TLV320AIC3x driver
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.
