Remove unnecessary 'n' defaults in audio modules. This doesn't affect any current build as 'n' is the default if not set otherwise. By removing the unconditional defaults, it becomes possible to set defaults later in board/family specific Kconfig.defconfig files. Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com>
SOF builds currently use the board Kconfig file to set any target specific build options. This includes modifying Zephyr build options (if different from Zephyr defaults for the SoC) and setting SOF specific options. There is currently no way to share definitions. For Intel ADSP boards, there starts to be a lot of boards and a lot of duplication of settings. Add a new mechanism to include common Kconfig.defconfig for a family of boards. Start with addition of boards/intel_adsp/Kconfig.defconfig and move common defaults for SOF audio modules to the common file. These are options that are not related to hardware features, but we want to set them in the same way for all Intel ADSP targets. Follow-up patches will move more options to the common Kconfig.defconfig and other vendors can add their own board family defconfig files. Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com>

Pull Request Overview
This PR implements shared common audio build options for Intel ADSPs to reduce code duplication across board configurations. The changes centralize default configuration values that were previously duplicated in individual board configuration files.
- Removes redundant
default nstatements from Kconfig files since this is the implicit default - Creates a centralized defconfig file for Intel ADSP platforms with common audio component defaults
- Removes duplicated configuration lines from individual Intel ADSP board files
