nice! Can some of these be removed completely? E.g. INTEL_MN looks Intel-specific, and we don't do XTOS builds on "main" any more?

Others are removed, but INTEL_MN seems to have more complex baggage still in place. I'm afraid the Zephyr SSP driver depends on this (still)... needs to be cleaned up before this can be merged.

@lyakh ok, now filed zephyrproject-rtos/zephyr#81734 for Zephyr and will submit a separate PR for SOF for this. I'll update this series to still keep INTEL_MN.
