ASoC: dt-bindings: tegra: Few more Tegra210 AHUB modules

This patch adds YAML schema for DT bindings of few AHUB modules.
These devices will be registered as ASoC components and bindings
will be used on Tegra210 and later chips. The bindings for below
mentioned modules are added:

 * SFC (Sampling Frequency Converter)
 * MVC (Master Volume Control)
 * AMX (Audio Multiplexer)
 * ADX (Audio Demultiplexer)
 * Mixer

title: Tegra210 ADX Device Tree Bindings
description: |
The Audio Demultiplexer (ADX) block takes an input stream with up to
16 channels and demultiplexes it into four output streams of up to 16
channels each. A byte RAM helps to form output frames by any combination
of bytes from the input frame. Its design is identical to that of byte
RAM in the AMX except that the data flow direction is reversed.

description: |
The Master Volume Control (MVC) provides gain or attenuation to a digital
signal path. It can be used in input or output signal path for per-stream
volume control or it can be used as master volume control. The MVC block
has one input and one output. The input digital stream can be mono or
multi-channel (up to 7.1 channels) stream. An independent mute control is
also included in the MVC block.
