audio: temporarily disabling auido-ull-playback feature

ULL playback does not enable COPP in the ADSP, meaning there is no
MaxxAudio tuning enabled. This means the vibration filtering in place in
MaxxAudio is not present in ULL, resulting in high vibration levels
which will cause discomfort in the user's hand.

Temporarily disabling the ULL feature to avoid this path being opened.
ULL will be re-enabled once the main fix is ready.
