Upstream sound card machine driver is used now and legacy machine driver
is not required anymore. Hence following cleanups are made:
- Remove legacy machine driver 'tegra_machine_driver.c'.
- With legacy driver removal many of the APIs in tegra_asoc_machine.c
are not required. So remove all such APIs and update the header file
as well.
- The ASoC utils 'tegra_asoc_utils.c' is not needed after removal of
legacy machine driver. Remove the corresponding header as well.
- BW manager support needs to be pushed in upstream and it is needed
for ADMAIF and ADSP ASoC drivers. The downstream BW manager code
can't be used by the ADMAIF driver. So remove downstream BW manager
code and put FIXME item in ADSP driver.

Added ADSP audio driver support for tegra soc and tegra virt alt.
Below are the changes made with respect to Kernel 5.10:
- Removed the ADSP COMPR DAI links due to differences in compress DAI
link registration in Android (ACK 6.6) which causes build issues.
- Omitted the callback function for dumping ADMA registers, as the
upstream ADMA driver does not support it.

DAI links are getting parsed in a reverse order with Kernel OOT,
where the DAI link nodes are now defined in overlays which gets
applied to the upstream DTB. Due to this PCM and compress devices
get a very large number which makes existing applications fail.
This seems to be expected as the overlay subnodes are merged just
after the parent properties. Each subnode comes just after the
properties. Because of this the later merged subnodes come before
the earlier merged nodes and eventually the DAI link nodes, in
this case, get reversed.
Given above it would be better to not assume DAI link node order.
To fix this use full name of DAI link nodes and identify the DAI
link index from it during parsing in kernel. The DAI link nodes
are named as 'nvidia-audio-card,dai-link@<xxx>', where <xxx>
signifies link index. Parse this info and store it under DAI link
ID. With this the PCM and Compress device IDs do not depend anymore
on the parsing order of DAI links.

Upstream Linux kernel commit 3989ade2d1e7 ("ASoC: soc.h: remove
num_cpus/codecs") removes the 'num_cpus' member from the
'snd_soc_pcm_runtime' structure because this is also available under the
dai_link structure. This breaks building the Tegra ASoC drivers for
Linux v6.1 and so update the Tegra ASoC drivers to align the latest
mainline. Note that this also works for earlier kernel versions and so
no need to check for kernel version.

- In case ADSP OS is crashed during boot/boot has not

On later kernels 'snd_pcm_ops' structure is removed from the
'snd_soc_component_driver' and instead explicit callbacks were
provided in the component driver structure. In doing so ack()
callback was left out for PCM interface. This was probably
intentional because there are currently no users for this
callback in upstream.
But in downstream we have ADSP audio driver which relies on
this callback to communicate buffer positions with ADSP and
currently DMA transfer is not happening due to missing ack()
callback. Issue is fixed by exposing ack() callback from the
core.

Resolve linux-5.8-rc3 merge conflicts in k5.9 branch

Fix build errors in k5.9 branch after merge of linux-5.8-rc3

Commit 209e5c7b4144 ("drivers: fix k5.9 build errors") fixes few build
errors, associated with audio, which are required for initial kernel-5.9
setup. However there are functional issues on TOT, where APE sound card
registration fails. The root cause of this problem is because of below
listed changes in ASoC core:
- 'snd_soc_ops' member is removed from 'component_driver' structure.
The PCM callbacks now have to be directly populated in the component
driver structure. ADMAIF and ADSP drivers are updated and Tegra PCM
driver is cleaned up accordingly.
- 'of_node' and 'dev_name' members are removed from 'snd_soc_codec_conf'
structure now and instead wrapper for these is provided under 'dlc'.
- Signature of 'snd_soc_get_pcm_runtime()' has changed now and it no
more accepts DAI link name as argument. But since we require specific
'rtd' based on DAI link names, the older version is duplicated in
machine driver.
- There are changes in trigger() order for start and stop now.
*_trigger_start()
|
|--> rtd trigger()
|--> component trigger()
|--> dai trigger()
*_trigger_stop()
|
|--> dai trigger()
|--> component trigger()
|--> rtd trigger()
Above is resulting in following:
|-> start ADMA
|-> start ADMAIF
|-> ...
|-> stop ADMAIF
|-> stop ADMA (unable to stop DMA channel print is seen here)
Current order in downstream for previous kernel versions is:
|-> start ADMA
|-> start ADMAIF
|-> ...
|-> stop ADMA
|-> stop ADMAIF
This issue is addressed by invoking DMA trigger() call from ADMAIF dai
trigger() itself to avoid the error during stop.

This patch registers ADSP device as a component with ASoC core. Necessary
changes are made to work with 5.4 kernel and driver need not register a
separate platform and codec device.
Along with this following cleanup is done:
- Move driver to 'tegra' directory.
- Wherever possible, fix ACV issues in the driver. Not all of them can be
fixed at the moment.
