Starting with Cherryview, devices may have a varying number of EU for
a given ID due to creative fusing. Punit support different frequency for
different fuse data. We use this patch to help get total eu enabled and
read the right offset to get RP0

Based upon a patch from Jeff, but reworked to only store eu_total and
avoid sending info to userspace

When we transitioned to the atomic plane helpers in commit:

            drm/i915: Move to atomic plane helpers (v9)

one of the changes was to call intel_plane_destroy_state() while tearing
down a plane to prevent leaks when unloading the driver.  That made
sense when the patches were first written, but before they were merged,

        commit 3009c037
        Author:     Thierry Reding <treding@nvidia.com>
        Date:       Tue Nov 25 12:09:49 2014 +0100

            drm: Free atomic state during cleanup

had already landed, which made this the responsibility of the DRM core.
The result was that we were kfree()'ing the state twice, and also
possibly double-unref'ing a framebuffer, leading to memory corruption
when the driver was unloaded.

The fix is to simply not try to cleanup the state in the i915 teardown
code now that the core handles this for us.

The rotation property is shared by multiple drivers, so it makes sense
to store the rotation value (for atomic-converted drivers) in the common
plane state so that core code can eventually access it as well.

Note that this patch removes a call to manager->ops->commit() in

fimd driver to set underlying timings and need only in full modeset
operations. For plane update only win_commit is needed.

struct exynos_drm_overlay has no practical advantage nor serves as
important piece of the exynos API design. The only place it was used
was inside the struct exynos_plane which was just causing a extra
access overhead. Users had to access the overlay first and just then
get the plane information it contains.

This patch merges struct exynos_drm_overlay into struct exynos_plane.
It also renames struct exynos_plane to struct exynos_drm_plane.

The rational is to cut one step to access plane information.
