We have a long history of adding these Intel audio device IDs that are
only used once, which is not our usual practice per the comment at the
top of the file:

 *      Do not add new entries to this file unless the definitions
 *      are shared between multiple drivers.

Generally speaking, if an ID is used by only a single driver, we
either use the plain hex ID or add the #define to the driver that uses
it.

Have we been operating under some special exception for the Intel
audio IDs?  I see that I acked some of these additions in the past,
but I don't remember why.
