Bluetooth: Add BT_HS config option

Move A2MP Module under BT_HS config option and allow the user have flexible option to choose the feature only they need a2mp_discover_amp() & a2mp_channel_create() are a2mp module entry point for master and slave, and this is dynamic invoked depends on the userspace or remote request, then we defined their implementation depends on BT_HS config Signed-off-by: Arron Wang <arron.wang@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
