arm64: tegra: Sort nodes by unit-address, then alphabetically

Nodes in device tree should be sorted by unit-address, followed by nodes
without a unit-address, sorted alphabetically. Some exceptions are the
top-level aliases, chosen, firmware, memory and reserved-memory nodes,
which are expected to come first.

These rules apply recursively with some exceptions, such as pinmux nodes
or regulator nodes, which often follow more complicated ordering (often
by "importance").

While at it, change the name of some of the nodes to follow standard
naming conventions, which helps with the sorting order and reduces the
amount of warnings from the DT validation tools.

Regulators defined at the top level in device tree are no longer part of

reg property shouldn't have a unit-address either, so drop the unit
address from the node names. To ensure nodes aren't duplicated (in which
case they would end up merged in the final DTB), append the name of the
regulator to the node name.

arm64: tegra: Extend APE audio support on Jetson platforms

Extend APE audio support by adding more audio components such as SFC,
MVC, AMX, ADX and Mixer. These components can be plugged into an audio
path and required processing can be done. ASoC audio-graph based sound
driver is used to facilitate this and thus extend sound bindings as
well.

The components in the path may require different PCM parameters (such
as sample rate, channels or sample size). Depending on the pre-defined
audio paths, these can be statically configured with "convert-xxx" DT
properties in endpoint subnode. The support for the rate and channel
conversion is already available in generic audio-graph driver. Sample
size conversion support can be added based on the need in future.

The support is extended for following platforms:
* Jertson TX1
* Jetson Nano
* Jetson TX2
* Jetson AGX Xavier
* Jetson Xavier NX

arm64: tegra: Consolidate audio card names

The current scheme for audio card names is suboptimal because it causes
the automatically generated names (for ID and driver) to be truncated,
which in turn can cause conflicts.

Introduce a new scheme which reuses the board model for the names and
appends the "HDA" and "APE" suffixes for the HDA and APE, respectively.
As a side-effect these suffixes end up being used as the ID of the SoC
sound cards which makes it easy for users to select them when using the
ALSA command-line utilities, for example.

As a separate measure, the driver name for the cards is now set by the
corresponding audio driver (either tegra-hda or tegra-ape), making it a
more useful identifier than the currently normalized card name.

arm64: tegra: Disable the ACONNECT for Jetson TX2

Commit ff4c371d2bc0 ("arm64: defconfig: Build ADMA and ACONNECT driver")
enable the Tegra ADMA and ACONNECT drivers and this is causing resume
from system suspend to fail on Jetson TX2. Resume is failing because the
ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT
driver is attempting to power on a power-domain that is provided by the
BPMP. While a proper fix for the resume sequencing problem is identified,
disable the ACONNECT for Jetson TX2 temporarily to avoid breaking system
suspend.

Please note that ACONNECT driver is used by the Audio Processing Engine
(APE) on Tegra, but because there is no mainline support for APE on
Jetson TX2 currently, disabling the ACONNECT does not disable any useful
feature at the moment.
