gen2/3 platforms have a boatload of rings we're not using. On my 830 the BIOS/hw can leave some of those "active" after resume which will prevent c3 entry. The ring is apparently considered active whenever head != tail even if the ring is disabled. Disable and clear all such unused ringbuffers on init/resume.
