ASoC: rt5514: Fix event generation for "DSP Voice Wake Up" control

The driver has a custom put function for "DSP Voice Wake Up" which does
not generate event notifications on change, instead returning 0. Since we
already exit early in the case that there is no change this can be fixed
by unconditionally returning 1 at the end of the function.
