ASoC: wm2000: Fix wrong value references for boolean kctl

commit 00a14c2968e3d55817e0fa35c78106ca840537bf 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.
