ASoC: madera: Fix event generation for OUT1 demux
madera_out1_demux_put returns the value of
snd_soc_dapm_mux_update_power, which returns a 1 if a path was found for
the kcontrol. This is obviously different to the expected return a 1 if
the control was updated value. This results in spurious notifications to
user-space. Update the handling to only return a 1 when the value is
changed.
