[PATCH 01/10] ASoC: SOF: sof-audio: Add a new op in struct sof_ipc_tplg_ops

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

Add a new host_config op in struct sof_ipc_tplg_ops and define it for
IPC4. This will be used to configure the host widget during prepare
after a suspend/resume or after an xrun.
