I'm struggling to see any reason not to just hold the external mute on
for the entire time the headset is powered off?

I think because it would mean in most cases that we keep a GPIO line enabled
during the time the HS is not in use, which burns power.
In most cases the mute is enabled when the GPIO line is up.

That makes sense if the GPIO is actively driven, open drain should be
better here, but it's still a generic thing which it'd be nice to
extract.

Still, the main thing here was the fact that we should be able to drop
the flag for the feature in the first place.
