So you are broadcasting 8800+ lines into every subdriver across the entire kernel. Just the time spent in the preprocessor parsing this will affect compilation time. Please implement separation of concerns. Move the register definitions into the drivers, and if they are too large, atleast make a local include file in sound/soc for the codec parts so the GPIO subdriver does not have to churn through all this to get its job done. I know there are other MFD drivers doing this but it's not a good pattern.
