dual microphone noise suppression should be used during a phone call
in handset mode. The disabling is performed by using the same A1026
settings as those used in Voice Recognition when not using the
Noise Suppression algorithm. This mode uses the exact same input
and gains as the incall receiver mode (A1026_PATH_INCALL_RECEIVER)
A new mode (A1026_PATH_INCALL_NO_NS_RECEIVER) is defined for code
clarity.
