audio: new audio devices enum values
Each audio device is identified by a bit in a 32 bit field with
16 bits for output devices and 16 bits for input devices.

identification is defined, allowing 31 different input and output
devices: Bit 31 of the bit field is reserved and when set indicates
an input device.
Also added new output device for wifi display and new input devices
for digital and analog docks, USB and wifi display send.
