This is more idiomatic and interacts better with deferred probing.

This is slightly more complex than a standard regmap conversion due to the moderately detailed cache control and the open coding of a register patch for the class D speaker on the TLV320AIC3007.
Although the device supports paging this is not currently implemented as the additional pages are only used during the application of the patch for the TLV320AIC3007.
