[SRU][OEM-OSP1-B][PATCH 0/1] Headphone doesn't work on two dell machines

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1836132

This patch is a SAUCE patch, because this patch is not upstreamed yet, but
we can't wait for it to be upstreamed due to the project schedule.

But Kailang is going to upstream this patch soon, and will cc stable,
so our other kernels like EAON, DISCO, COSMIC and BIONIC will get this
patch from stable patches. This SAUCE patch is only for OEM-OSP1-B.

[Impact]
We have two Dell machines and the headphone-mic doesn't work on
these two machines.

[Fix]
Because the pin 0x1b is connected to headphone-mic, we need to apply
DELL4 fixup to them

[Test Case]
Apply this patch and plug a pure mic to the audio jack, select headphone-mic
from "input source", then we can record sound from the headphone, it works
very well.

[Regression Risk]
Low. the change is just specific to these two machines.
