The ACPI scan capabilities is called from the intel-dspconfig as well as the SOF/HDaudio drivers. This creates dependencies and randconfig issues when HDaudio and SOF/SoundWire are not all configured as modules. To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and intel-dspconfig, move the ACPI scan helpers to a dedicated module. This follows the same idea as NHLT helpers which are already handled as a dedicated module. The only functional change is that the kernel parameter to filter links is now handled by a different module, but that was only provided for developers needing work-arounds for early BIOS releases.
