[PATCH BlueZ 4/6] bass: Create setups for all BISes in BASE

[Iulia Tanasescu <iulia.tanasescu@xxxxxxx>]

A BAP Scan Delegator (BASS Server) might be instructed by BAP Broadcast
Assistants (BASS Clients) to change sync between streams, via the Modify
Source operation. A Scan Delegator should create setups for all BISes
discovered in the BASE of a Broadcast Source, and create associated
streams based on Add Source/Modify Source commands received from
Assistants.
