Merge branch 'cpuidle/3.18' of https://git.linaro.org/people/daniel.lezcano/linux into pm-cpuidle

Pull ARM cpuidle changes for v3.18 from Daniel Lezcano:

"this pull request contains the following changes:

 * Lorenzo Pieralisi implemented a framework to initialize the ARM
   cpuidle drivers with the DT. As an example, it provided a couple of
   drivers using it: arm64 and big little. The former one is a new
   driver while the latter is a change. There was also a patch for
   Exynos allowing to use this framework but as it depends on a change
   in Samsung's tree, I postponed this patch until the change is visible
   after the merge. The set of changes depends on some other changes
   made in the ARM64 tree, for this reason a shared branch is used. This
   is why there is a merge from arm64 in my pull request. I believe we
   already used this procedure.

 * Kevin Hilman added the compatible string for the exynos 5800 in the DT"
