ASoC: q6adm: Add support for programmable channel mixer
The DSP supports programmable channel mixer to mix a given number of inputs to a given number of outputs. Add support in ADM to configure the programmable channel mixer. Change-Id: Ibce7d4b50d0d580f4223831a03411663d9c5c485 Signed-off-by: Bhalchandra Gajare <gajare@codeaurora.org>
