Add Tegra264 I2S support with following changes:
- Add soc_data for Tegra264-specific variations
- Tegra264 supports 32 RX and 32 TX ADMAIF channels and each ADMAIF
stream supports max 32 channels. To accommodate the change dais, CIF
configuration API and driver components are updated.
- Register offsets and default values are updated to align with Tegra264.

Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros
instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together
with pm_ptr(), which allows us dropping ugly __maybe_unused
attributes.
This optimizes slightly when CONFIG_PM is disabled, too.

Add interconnect framework support to set required audio bandwidth
based on PCM device usage. The maximum bandwidth is determined by
the number of APE PCM devices and maximum audio format supported.
If interconnect property is not defined or INTERCONNECT config
is not enabled then the audio usecase will still function.
Validate bandwidth updates by reading the interconnect summary sysfs
node during PCM device open and close operations.

Add support for S24_LE format for all internal and IO AHUB
modules, except for ASRC (which is already supported).
The data flow happens as mentioned below:
- ADMAIF picks 24-bit valid data and converts it to 32-bit before
sending to internal AHUB modules. This makes the driver change
simpler for internal AHUB modules.
- IO modules CIF converts the 32-bit data to 24-bit before sending it
to the external world.
- To maintain consistency across modules, conversions between 24-bit
and 32-bit occur either at ADMAIF or at the IO modules CIF.
This feature has been thoroughly tested and verified with all internal
AHUB modules on the Jetson AGX Orin Platform, as well as with the
external RT5640 codec.

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

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 ADMAIF driver accordingly.

convert imx-pcm-rpmsg driver to use that. This allows us to remove

ADMAIF is the interface between ADMA and AHUB. Each ADMA channel that
sends/receives data to/from AHUB must intreface through an ADMAIF channel.
ADMA channel sending data to AHUB pairs with an ADMAIF Tx channel and
similarly ADMA channel receiving data from AHUB pairs with an ADMAIF Rx
channel. Buffer size is configurable for each ADMAIF channel, but currently
SW uses default values.
This patch registers ADMAIF driver with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes ADMAIF interfaces, which can be used to connect different
components in the ASoC layer. Makefile and Kconfig support is added to
allow to build the driver. The ADMAIF device can be enabled in the DT via
"nvidia,tegra210-admaif" compatible binding.
Tegra PCM driver is updated to expose required PCM interfaces and
snd_pcm_ops callbacks.
