msm8937-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.
