The SelectProperties method is only called on the central (initiator)
device. But there's no information related to the remote device for which
is call is done.
These commits allow the audio server to link this call method to the
appropriate remote endpoint.
Changes in V2:
- Set endpoint part of the dictionary properties
- Pass rpac to select function instead of DBus specific path
- Add a new commit to keep consistency after fixing previous
patch for a checkpatch warning

2.25.1
This adds the remote endpoint path to the dictionary sent in
SelectProperties.
It allows audio application to know for which remote endpoint the call is
done and so for which it should act as an initiator.
