This patch adds echo canceling and noise reduction property to Handsfree
interface, allowing the handsfree unit to enable or disable this feature
in the audio gateway.
According to Bluetooth HFP 1.6 spec: By default, if the AG supports its
own embedded echo canceling and/or noise reduction functions, it shall
have them activated until the AT+NREC command is received.
