This patch will support multiple capture streams with DMIC. The pcm stream is composed of two pipelines: (1) copier host <- gain <- copier module (2) copier module <-gain <- copier DMIC. We need to use copier module to connect two pipelines because of the restriction with the ref FW that the gain module can only be connected to modules that are in the same pipeline Signed-off-by: Rander Wang <rander.wang@intel.com>
Currently copier components of the module type are used in pairs - one on each pipeline, connecting to each other. This isn't necessary. It's enough to have one such copier component on the side, that does forking. Add a single-copier capture pipeline variane and switch DMIC over to it.

The second capture stream can be used as a reference stream for user. Signed-off-by: Rander Wang <rander.wang@intel.com>
Use the simplified pipeline with just one module-type copier connecting two pipelines. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
Insert a second copier into the DMIC stream to generate a total of tree PCMs from it. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
