TWSP-A2DP: disconnect current TWSP device while connect unpaired TWSP device

In below scenario, only AVDTP is connected for EB1 of Set1 and only HFP for
EB3 of Set2:
TWS+ Set1: (EB1, EB2)
TWS+ Set2: (EB3, EB4)
1) Connect TWS+ device EB1 of Set1 first
2) Then connect another TWS+ device EB3 of Set2
3) HFP will disconnect EB1 and setup new connection to EB3
4) But A2DP will keep connection to EB1 and reject connection to EB3

Need change A2DP connection behaviour so that it will disconnect old earbud
connection and allow connection for new earbud in this case.
