 e11aa36  breaks suspend on at least lenovo x61

After solving  the conflicts, I applied the revert (see attachment) to
v3.18.7. I think it should also apply to the current head. With that
patch, suspend is working again on that version.

However, I have not to deep knowledge of that subsystem, so please,
someone who have, have a deeper look into it. I especially do not know
if the lines in .../intel_pm.c are correct or better leaving them as
they are in v3.18.7.

I want to have it working on a version that I know is stable before
asking to pull it to head.

Regards
   Klaus
