Subject: [PATCH 2/4] ASoC: SOF: imx: Use the generic helper to get the reply

From: Peter Ujfalusi <peter.ujfalusi@...ux.intel.com>

Make use of the generic snd_sof_ipc_process_reply() from the core instead
the local implementation.
snd_sof_ipc_process_reply() handles the reply retrieving and the ipc reply
