configs: Disable ULL audio path for SDM660 

Remove AUDIO_OUTPUT_FLAG_RAW flag from audio_policy
which is used for ultra-low-latency audio path as its not
fully supported and causes playback issues.
Solution: Use low-latency audio path instead.
Issues Fixed:
1. CTSHELP-4996:AudioLoopbackLatencyActivity fails in CtsVerifierTests
2. IOTBUG-4336: MIDI playback has glitches during playback.
