This adds APE sound card support on Jetson Nano and TX1 which is based on simple-card driver. Earlier in the series simple-card driver is enhanced to work with multiple ASoC components. Based on board design required I/O interfaces are exposed for I2S and DMIC. More complicated audio paths will be added going forward.
