[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1857496

[Impact]
There is a heaset jack on the dock, after resume, the mic on that jack
can't record sound anymore, need to close the recording app then reopen
that app to workaround this issue.

[Fix]
set the interface and EP, then the mic can record sound again.


[Test Case]
test the kernel with this patch, the mic can record sound after resume.

[Regression Risk]
Low, this quirk is specific to WD19 (usb vednor and device id).
