Subject: [PATCH 06/11] bluetooth: fix headset=auto ofono handover

Native backend implements HFP AG but not HFP HF yet, therefore headset=auto
functionality is still needed if HFP HF is required.

To make headset=auto work again, drop both HFP AG and HSP AG roles while
performing handover from native backend when oFono is detected running.

While at it, restore profile description to Headset Head Unit (HSP/HFP)
to note that HFP may be still provided via oFono backend.
