Bug Description

On the Asus X101CH, only the headphone part of the headset jack works by default, not the microphone.

This bug is for tracking purposes. Please do not triage.

With this patch, a TRRS headset mic cannot be successfully detected
on the Asus X101CH, and we can also distinguish between headphone
and headset automatically.

Now that we have better headset mic support infrastructure, I remembered I forgot
to upstream this patch. It was originally provided by Realtek (therefore, I cannot
answer for the msleeps and exactly why this is needed). I just rewrote it for the
current kernel version.
