topology: aw88399: define custom deepbuffer routing to smart amp

Disable HDA config's built-in deepbuffer (which routes to HDA analog codec)
and define our own deepbuffer PCM 31 that routes to the AW88399 smart amp.

This prevents routing conflicts where mixin.15.1 would have two outputs
(one to HDA mixout.2.1 and one to smart amp mixout.20.1).

Routes:
- Regular playback (PCM 0): mixin.1.1 → mixout.20.1 → smart_amp → SSP1
- Deepbuffer (PCM 31): mixin.15.1 → mixout.20.1 → smart_amp → SSP1
