[PATCH v1 2/3] ASoC: meson: Fix event generation for AUI CODEC mux

The AIU CODEC has a custom put() operation which returns 0 when the value
of the mux changes, meaning that events are not generated for userspace.
Change to return 1 in this case, the function returns early in the case
where there is no change.
