ASoC: meson: Fix event generation for AUI ACODEC mux
commit 2e3a0d1bfa95b54333f7add3e50e288769373873 upstream.
The AIU ACODEC 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.
