ASoC: tegra: Fix kcontrol put callback in I2S 

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: c0bfa98349 ("ASoC: tegra: Add Tegra210 based I2S driver")
