It just doesn't seem to be logically a part of the codec code. And I didn't register
an spi device. I just linked the simple spi routines with my board code (separate file).
Plus, it seems a lot of code duplication if each codec registers the spi device
and I2C device. Are there more boards, or more codecs???
