universal7904: Remove references to a2dp module

APM would fail to parse the config anyway:

  E DevicesFactoryHAL: loadAudioInterface couldn't load audio hw module audio.a2dp (No such file or directory)
  W DevicesFactoryHalHidl: The specified device name is not recognized: "a2dp"
  E AudioFlinger: loadHwModule() error -22 loading module a2dp
  W APM_AudioPolicyManager: could not open HW module a2dp
