[PATCH 10/10] arm64: tegra: Audio graph sound card for Jetson Nano and TX1

[Sameer Pujar <spujar-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

Enable support for audio-graph based sound card on Jetson-Nano and
Jetson-TX1. Depending on the platform, required I/O interfaces are
enabled.

 * Jetson-Nano: Enable I2S3, I2S4, DMIC1 and DMIC2.
 * Jetson-TX1: Enable all I2S and DMIC interfaces.
