Pull Request Overview
This PR fixes build failures caused by incomplete API migration in the audio_stream_invalidate() function. Two calls to the deprecated dcache_invalidate_region() API were missed during the cache API refactor and are now updated to use the new Zephyr cache API.
- Replace remaining dcache_invalidate_region() calls with sys_cache_data_flush_range()
- Complete the cache API migration that was previously started in commit f78acf4

The function name is audio_stream_invalidate() but the implementation uses sys_cache_data_flush_range() instead of sys_cache_data_invd_range(). For cache invalidation, you should use sys_cache_data_invd_range() which invalidates cache lines without writing back dirty data, whereas flush_range() writes back and then invalidates.

Fix remaining calls to old dcache_invalidate_region() API in the audio_stream_invalidate() function that were missed during the cache API migration. Replace with proper sys_cache_data_invd_range() calls. The previous refactor left two calls to the old API which causes build failures. Fixes: f78acf4 ("audio: use zephyr/cache.h for cache flush/invalidate") Signed-off-by: Tomasz Leman <tomasz.m.leman@intel.com>
