[PATCH BlueZ v2 2/3] bass: Create BASS session with Broadcasters

[Iulia Tanasescu <iulia.tanasescu@xxxxxxx>]

In the BASS plugin, BAP sessions created with scanned Broadcasters are
notified in the bap attached callback. This creates BASS data for these
devices as well, to internally keep information about the sessions.
