I tested this series without the last 2 patches on top of v3.5 and
suspend/resume hangs on 3430/n900, 3530/Overo, 3730/OveroSTORM, but
suspend/resume and cpuidle tests for retention and idle seem to work
fine on 3730/Beagle-xM.

It works fine on all the platforms with the last 2 applied (note 6/8
needs a minor update to apply cleanly to mainline v3.5.)
