This series adds resource-managed OPP API helpers and makes drivers
to use them.

Changelog:

v2: - This is a continuation of the work that was started by Yangtao Li.
      Apparently Yangtao doesn't have time to finish it, so I
      (Dmitry Osipenko) picked up the effort since these patches are
      wanted by the NVIDIA Tegra voltage-scaling series that I'm
      working on.

    - Fixed the double put of OPP resources.

    - Dropped all patches that are unrelated to OPP API. I also dropped
      the Tegra memory patch since it doesn't apply now and because I plan
      to switch all Tegra drivers soon to a common tegra-specific OPP helper
      that will use the resource-managed OPP API anyways.

    - Squashed couple patches into a single ones since there was no
      good reason to separate them.

    - Added acks that were given to a couple of v1 patches.
