This commit introduces a new devicetree property, bits-per-symbol, to
allow the symbol width to be configured from 3 to 8 bits. This change
is particularly beneficial for MCUs that lack DMA for their SPI
peripheral and have a limited hardware FIFO.
This property provides flexibility by allowing developers to select a
slower SPI clock frequency and use the symbol width to scale the
timings to meet strict LED strip requirements, minimizing the risk of
FIFO underruns.
Additionally, using higher-density patterns (e.g., 3-bit or 4-bit
symbols) makes more efficient use of the pixel buffer, which reduces
the RAM footprint required for the LED strip data.
The implementation is optimized with a fast path for the common 8-bit
symbol case, while a generic bit-packing loop handles all other
widths.

Remove INPUTMUX interrupt assignments for PINT and GPIO peripherals.
Remove gpio0 DT node.
As the GPIO peripherals can be secured on the mimxrt798s, accesses from
the cm33_cpu0 and hifi4 are mutually exclusive, so the GPIO0 will stay
enabled in the cm33_cpu0 domain.

Introduce the ACE 4.0 architecture, along with support for the NVL and
NVL-S platforms within the Intel ADSP framework in the Zephyr project.
This update includes:
- Addition of ACE 4.0 architecture configurations in Kconfig and
Kconfig.intel_adsp.
- Inclusion of device tree source files for NVL and NVL-S platforms,
defining CPU, memory, and peripheral configurations.
- Updates to driver files to support ACE 4.0 specific features,
including DMIC and SSP configurations.
- Introduction of new header files for ACE 4.0, detailing boot,
interrupt, IPC, power, and shim functionalities.
- Modifications to the CMakeLists.txt to include ACE 4.0 MMU support.
- Addition of default configurations for NVL and NVL-S platforms in
Kconfig.defconfig.ace40.
The NVL and NVL-S platforms are part of the Nova Lake series, targeting
advanced audio processing capabilities. ACE 4.0 introduces enhanced DSP
capabilities and advanced power management features, improving audio
stream handling and synchronization compared to ACE 3.0.
