Introduce a new component to perform configurable audio post processing
on playback path before smart amplifier.
1. Put google_audio_post_processing libs at $SOF_REPO/third_party/lib
- libgoogle_audio_post_processing.a
- libc++.a
- libc++abi.a
2. Enable google_audio_post_processing in config override
$SOF_REPO/src/arch/xtensa/configs/override
CONFIG_COMP_GOOGLE_AUDIO_POST_PROCESSING=y
3. Build the firmware and tool with xcc
4. To verify it works:
- aplay some audio
- amixer and grep GAPP
- sof-ctl to get/set control
