ASoC: tegra: Fix kcontrol put callback in ADMAIF

Browse source

commit e2b87a18a6 upstream.

The kcontrol put callback is expected to return 1 when there is change
in HW or when the update is acknowledged by driver. This would ensure
that change notifications are sent to subscribed applications. Update
the ADMAIF driver accordingly.
