Add Tegra264 I2S support with following changes:
- Add soc_data for Tegra264-specific variations
- Tegra264 I2S supports 32 audio channels, hence update the TDM config,
CIF configuration API and DAI channel_max parameter.
- Register offsets and default values are updated to align with Tegra264.

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.

The AHUB HW modules are interconnected with CIF which are capable of
supporting Channel and Sample bit format conversion. Due to this, the
I2S Client can have different Channel and Sample bit from the hw_params()
and this config is passed from CIF port of I2S DT node which can help to
perform this conversion.
For e.g. HFP usecase consists of BT SCO with 1ch and 8k audio data
which needs to be converted and mixed with external codec playback and
capture path which is of 2ch and 48k format.
For HFP Playback:
The path includes mono to stereo and 8k to 48k conversion
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
| |1ch | | 1ch | |2ch | SFC | 2ch | |
|BT SCO |---->| I2Sx |------>| CIF |----->| 8k->48k |---->| Codec I2Sy|
|_ _ _ _| |_ _ __|client |_ _ _|audio |_ _ _ _ _| |_ _ _ _ _ _|
For HFP Capture:
The path includes stereo to mono and 48k to 8k conversion
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
| | 2ch | SFC | 2ch | | 1ch | | 1ch | |

|_ _ _ _ _ _| |_ _ _ _ _| audio|_ _ _|client |_ _ _ _| |_ _ _ _|
For above two path, I2S client channel uses existing DT binding to pass
channels and format conversion in I2Sx CIF Port.

The Inter-IC Sound (I2S) controller implements full-duplex, bi-directional
and single direction point to point serial interface. It can interface
with I2S compatible devices. Tegra I2S controller can operate as both
master and slave.
This patch registers I2S controller with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes I2S 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 I2S devices can be enabled in the DT via
"nvidia,tegra210-i2s" compatible binding.
