CS46xx driver switches the buffer depending on the number of periods, and in some cases it switches to the own buffer without updating the buffer type properly. This may cause a problem with the mmap on exotic architectures that require the own mmap call for the coherent DMA buffer.
This patch addresses the potential breakage by replacing the buffer setup with the proper macro. It also simplifies the source code, too.

This change is superfluous for 5.14. Please drop.
