Subject: [PATCH 2/2] ASoC: SOF: Intel: hda: Set the mic_privacy flag for soundwire with ACE3+

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

The microphone privacy feature is introduced with ACE3, the soundwire
driver needs to know this to be able to print the PVCCS register via
register dump in sysfs.
