This patch is based on the two patches of
https://lists.ubuntu.com/archives/kernel-team/2018-February/090186.html, the two
patches are not sufficient to fix headset-mic problem on the machine with the
codec alc289, with those two patches, the driver can detect that the headset-mic
is plugged, but can't record sound with headset-mic.

Thanks to Kailang at realtek, he pointed out that FIXUP for alc289 is wrong, so
we need to apply this new patch to fix the problem.

[Test Case]
plug the headset and record the sound on the machine with the codec alc289

one commit from alsa repository, and this commit will be merged to upstream soon.

[Regression Potential]
very low, since this patch only change the FIXUP for the Dell machines with
alc289, and we already verified both plug detection and recording sound work
well with the new patch.
