In this case, it looks like the right channel records noise rather
than the inverted signal, but the simplest way is to just call it
"Inverted Internal Mic", which will cause it to be muted by default.

From what I can see, the generic parser is now good enough to handle
Realtek's inverted dmic handling, so let's remove the special handling
and use the generic parser instead.
