Lack of camera prevents suspend in OFW

Quanta reported to me a higher than expected power draw in suspend and we tracked it down to them not having a camera installed. If the camera is not present then although the system appears to go into suspend its not all the way down. The power LED does not go out and the USB power is not disabled. Both indications that the EC is not detecting the SoC in suspend.
Blacklisting the camera drivers in Linux does not duplicate the problem. I have not yet tested with Linux without a camera installed.
