hal: Fix aanc sequence during voice call

When aanc is enabled during voice call, TX and RX  path mixer
controls are issued back to back, this causes the codec path to be
enabled from TX to RX as the internal loopback for aanc exists. Due
to enabling this path, mute is observed on handset. This issue
is fixed by treating aanc as special usecase and changing the enable
and disable sequence of aanc mixer controls.
