[0/9] add ASoC components for AHUB

Overview
========
The Audio Hub (AHUB) is part of the Audio Processing Engine (APE) which
comprises a collection of hardware accelerators for audio pre-processing
and post-processing. It also includes a programmable full crossbar for
routing audio data across these accelerators.

This series exposes some of these below mentioned HW devices as ASoC
components for Tegra platforms from Tegra210 onwards.
 * ADMAIF : The interface between ADMA and AHUB
 * XBAR   : Crossbar for routing audio samples across various modules
 * I2S    : Inter-IC Sound Controller
 * DMIC   : Digital Microphone
 * DSPK   : Digital Speaker

Following is the summary of current series.
 1. Add YAML DT binding documentation for above mentioned modules.
 2. ACIF programming is same for Tegra generations and hence it is moved
    to a common file.
 3. Add ASoC driver components for each of the above modules.
 4. Add DT entries for above components for Tegra210, Tegra186 and
    Tegra194.
 5. Enable these components for Jetson-Tx1, Jetson-Tx2 and
    Jetson-Xavier.

Machine driver series will be sent separately.
