Tools: Topology: Add deep buffer capture option for DMIC
If DMIC0_DEEP_BUFFER is defined as true in topology build a deep buffer capture PCM is branched from module copier in DMIC0 capture pipeline. The patch adds a pipeline class deepbuffer-capture.conf and a topology .conf snippet dmic-deep-buffer.conf that is conditionally included from dmic-generic.conf.
