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.
