[PATCH BlueZ 01/13] audio: Remove HFP and HSP headset role support

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

The support for these profiles are intended to be external, probably directly
integrated in the telephony stack of the platform in use e.g. oFono.
