binding: telephony: remove bluetooth dependency
By subscribing to org.ofono.Modem PropertyChanged events it can be detected when a handsfree profile device is connected. In turn the bluetooth service access is no longer needed. Bug-AGL: SPEC-2117 Change-Id: Iae92c66962ac88e07d58d75e566ae31e7128c831 Signed-off-by: Matt Ranostay <matt.ranostay@konsulko.com>
