Subject: [PATCH v3 6/6] ASoC: qcom: audioreach: add support for SMECNS module

From: Srinivas Kandagatla <srinivas.kandagatla@....qualcomm.com>

This patch adds support for Single Mic ECNS module, used for echo
cancellation. It also makes use of audioreach_set_module_config to load
the calibration data for this module from ASoC tplg file.
