sm6375-common: audio: Disable ULL mode

Browse Source 
- Ultra low latency playback is currently broken. Crackling audio
  can be well noticed while playing WhatsApp audio messages or even
  during some games.

- This patch routes all audio that normally used audio-ull-playback
  paths to low-latency-playback paths instead, thus meaning we're
  switching from ULL to LL mode.
