Few Carkits Like "VW MI" & "Seat BT AC" will register the ADVANCED
AUDIO UUID rather than A2DP SINK UUID. Once the signalling channel
is initiated by the remote sink device and streaming channel is not
yet initiated by sink, the source will check the remote device
SINK UUID to establish the streaming channel and will close the
signalling channel if SINK UUID is not present.
In addition to A2DP SINK UUID, this patch checks for the ADVANCED
AUDIO UUID as well.
