AHAL: add API to notify the HAL module about disconnecting device.

Browse Source 
When external device is about to disconnect, the audio framework will
notify the HAL module about the coming device disconnection so that the
HAL module could abort any active read/write operations on drivers to
avoid problems with the HW interfaces.
