Subject: ASoC: tas2552: Fix kernel crash caused by wrong kcontrol entry

From: Peter Ujfalusi <peter.ujfalusi@ti.com>

commit 1cf0f44811b754b64283b11ef0e60cb0de07b29c upstream.

SOC_DAPM_SINGLE("Playback AMP", ..) should not be under kcontrols. It
causes kernel crash (NULL pointer) when the mixers are listed.
