Add "c_terminal_type" and "p_terminal_type" configfs entries in order to allow the user to change the capture and playback terminal type codes. These fields affect the type of audio device that Windows detects, so being able to modify this is useful when it would be advantageous for a gadget to be detected as something other than a generic speaker/microphone. The fields default to microphone for the capture type field and speaker for the playback type field as was the case before.
