Do Elans even support S3?

I'm just not sure how many suspend/resume cycles people really do
on a early (pre -rc) mainline kernel (or in linux-next for that
matter). You usually have to install on a laptop and actually
use it.

Since this code is only executed on resume some directed testing
would be better. That is what Rafael asked for in this mail.

I think it would be ok for .26 if we can get confirmation it works
on a few systems with S3 suspend/resume.
