Add support for the Nuvoton NAU83G60 audio codec. The NAU83G60 is a
stereo 30W+30W smart amplifier with an integrated low-latency
Advanced Audio DSP.

Changes in v3:
- Add Kconfig and Makefile entries for the building system.
- Change block comments to C++ style.
- Add initialization for 'data_count' before usage.
- Fix a potential stack buffer overflow in DSP reply parsing by adding a strict 'data_count <= 0' check.
- Replace magic numbers with descriptive macros.
- Return -EBUSY in `nau8360_dac_mux_put_enum()` to prevent playback disruption.
- Remove the 'GFP_DMA' flag as DMA memory is not strictly required here.
- Convert multiple 'if' statements to 'switch' statements.
- Remove internal hardware debugging code for GPIO1 to GPIO3.
- Initialize TDM slot arrays to resolve `nau8360_set_tdm_slot()` setup failures.
- Fix event_missing and event_spurious in TDM/PEQ put functions.
- Fix uninitialized variable usage in TDM slot put.
- Add "Slot None" mapping with custom _get functions, and optimize I2C reads for this state.
- Refactor TDM slot validation into nau8360_validate_tdm_slots().
