The mixer core on the Arizona devices is powered up whenever any routing is non-zero. This patch saves a little power and avoids a few difficult corner cases (around the mixer core being powered whilst there is no clock available), by using the autodisable mux functionality to only write out the settings for the muxes when they are powered up.
