The vast majority of the wm_adsp_setup_algs function is case statements for ADSP1 or ADSP2, this patch splits this out into two separate functions wm_adsp1_setup_algs and wm_adsp2_setup_algs. The small amount of shared code between them is factored out into an extra helper function. This makes the code a lot cleaner.
