Bug description:

  To fix this bug, B/OEM-B/C needs only 1 patch, while v5.0-rc1 introduced
  a new patch which affect this issue, so the DISCO needs 2 patches.

  After S3, some codecs (alc236, alc255, alc891 and some HDMI codec) stop
  working, they can't detect jack plugging/unplugging or the audio device
  can't show up in the gnome-sound-setting

  After S3, if it runs runtime_resume(), the codec works again. We change
  the driver to let system_resume() trigger runtime_resume()

  [Test Case]
  This issue is reported from OEM project, some codecs can't detect
  jack pluggin/unplugging, some codecs can't show up in the UI, after
  applying this patch, all related bugs are fixed.

  [Regression Potential]
  Low. have tested on many machines (with this issue or without this issue),
  all worked well.
