ASoC: wm8904: Fix wrong value references for boolean kctl

commit eaddf6fd959074f6a6e71deffe079c71eef35da6 upstream.

The correct values referred by a boolean control are
value.integer.value[], not value.enumerated.item[].
The former is long while the latter is int, so it's even incompatible
on 64bit architectures.
