ASoC: tegra: Fix kcontrol put callback in I2S

commit f21a9df3f7cb0005947679d7b9237c90574e229a 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 I2S driver accordingly.

Fixes: c0bfa98349d1 ("ASoC: tegra: Add Tegra210 based I2S driver")
