** Description changed:

- need to cat /proc/asound/cardX/codecX to trigger it work again.
+ 
+ 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.
+ 
+ [Impact]
+ 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
+ 
+ [Fix]
+ 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.
