bluez5-dbus: Track ASHA HiSyncId & Side information in transport

Browse source 
ASHA devices with the same HiSyncId are a pair and this
will be used later on to set them up together with a
combine sink like device set for BAP. Side information
is required for channel information when setting up the
combine sink.
