The function only really needs dev_priv to make its decision. If we
ever need more, we can change it again. But then, in this case we
should make needs_memory_bw_wa be a variable inside struct
skl_wm_params so we won't need to keep passing intel states deep
inside pure watermark value calculation functions.
