For upstream initially ADMAIF and I/O modules are considered. And the
these drivers are rebased in previous commit. This patch tracks the
addition of DAIs in AHUB driver which are needed for other AHUB modules.

AHUB and few components have been pushed for upstream review. Though the
changes are still under review, we can leverage the work done on upstream
5.x and use the same here on 5.4 kernel. This helps to align the downstream
code. Any changes that happen because of upstream review can be cherry
picked here. If we plan for any downstream changes, upstream patch needs to
be pushed to keep the code in sync.
As of today current snapshot is pulled from v3 of AHUB series,
http://patchwork.ozlabs.org/project/linux-tegra/list/?series=159664
Above series was worked on later versions of linux-next and hence following
are the changes required for porting back on 5.4
* tegra_pcm_new() and tegra_pcm_free() are exposed from tegra_pcm.c and
component driver callbacks use these.
* Callback functions required for snd_pcm_ops in component driver are
implemented by tegra_pcm.c
* With this ADMAIF driver need not register platform device with ASoC
core.
For components (AHUB, ADMAIF, I2S, DMIC and DSPK) the downsream code
differs in few aspects from the code that was pushed for v3. Some of them
are listed below.
* I2S driver in downstream implements startup()/shutdown() calls for DAI,
which does some setup related to pinconfig and regulators. The same is
true for DMIC and DSPK drivers as well.
* Downstream ADMAIF drivers makes bandwidth requests in startup/shutdown()
calls and has helper function for dumping registers. It also has
additional DAI interfaces which are used for ADSP audio.
* Downstream AHUB driver has DAI interfaces for connecting to all other
modules.
These differences will be cherry-picked as and when it is necessary.

Tegra210 and later audio drivers have been using 'tegra-alt' directory
from the beginning. As per the upstream roadmap, we plan to use the
same 'tegra' directory and place all the drivers under it. This patch
thus moves all the drivers to 'tegra' and renames the files accordingly.
The '_alt' suffix is removed from header and source files.
For some files still the '_alt' suffix is retained because 'tegra'
already has the corresponding files. Manual merge of following files is
needed and will be done in separate commits.
* tegra_asoc_utils_alt.c and tegra_asoc_utils.c
* tegra_asoc_utils_alt.h and tegra_asoc_utils.h
* tegra_pcm_alt.c and tegra_pcm.c
* tegra_pcm_alt.h and tegra_pcm.h
* Corresponding Makefile and Kconfig files.
* Source files related to ADSP audio, FPGA, bandwidth manager are not
considered at the moment and will be tracked separately.
