Subject: [PATCH] op5: enable split A2DP to implement A2DP encoding offload

* "Split A2DP" probably stands for splitting A2DP output
  stream out from A2DP HAL to primary audio HAL, which
  makes it possible to offload SBC / aptX / AAC ... encoding
  to DSP.

* Primary audio HAL requires libbthost_if to transmit BT
  packets.
