ASoC: tegra: AHUB routes for OPE module
Add AHUB routes for OPE module. The OPE module can be plugged into audio
path as per the need. The routing controls can be used to setup the audio
path with OPE similar to the already existing routes. The support is added
on Tegra210 and later Tegra SoCs where OPE module is present.

ASoC: tegra: AHUB routes for ASRC module
Add AHUB routes for ASRC module. The ASRC module can be plugged into audio
path as per the need. The routing controls can be used to setup the audio
path with ASRC similar to the already existing routes. The routes are added
to Tegra186 and later Tegra SoCs where ASRC module is present.

ASoC: tegra: Update AHUB driver for Tegra234
The register offsets of switches connecting various AHUB internal
modules have changed from previous chip. Address this variation by
making use of Tegra234 based compatible.

ASoC: tegra: Fix kcontrol put callback in AHUB
The kcontrol put callback is expected to return 1 when there is change
in HW or when the update is acknowledged by driver. This would ensure
that change notifications are sent to subscribed applications. Update
the AHUB driver accordingly.

ASoC: tegra: Add routes for few AHUB modules
Add routing support for following modules of AHUB:
 * SFC (Sampling Frequency Converter)
 * MVC (Master Volume Control)
 * AMX (Audio Multiplexer)
 * ADX (Audio Demultiplexer)
 * Mixer

These modules can be plugged into audio path as per the need using
routing controls similar to the already existing routes to I/O modules
such as I2S, DMIC and DSPK.

ASoC: tegra: Add Tegra210 based AHUB driver
The Audio Hub (AHUB) comprises a collection of hardware accelerators for
audio pre/post-processing and a programmable full crossbar (XBAR) for
routing audio data across these accelerators in time and in parallel.
AHUB supports multiple interfaces to I2S, DSPK, DMIC etc., XBAR is a
switch used to configure or modify audio routing between HW accelerators
present inside AHUB.

This patch registers AHUB component with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes AHUB interfaces, which can be used to connect different
components in the ASoC layer. Currently the driver takes care of XBAR
programming to allow audio data flow through various clients of the AHUB.
Makefile and Kconfig support is added to allow to build the driver. The
AHUB component can be enabled in the DT via below compatible bindings.
  - "nvidia,tegra210-ahub" for Tegra210
  - "nvidia,tegra186-ahub" for Tegra186 and Tegra194
