[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.
