drm/i915: Performed deferred clflush inside set-cache-level

Currently we are hitting the WARN inside
i915_gem_object_set_cache_level() as we can now have an unbound object
in the GTT write domain (due to 43566dedde54f9 "drm/i915: Broaden
application of set-domain(GTT)"). To avoid the warning, we need to track
when we elided the clflush on a cacheable object and then evict the
cache for the object when we move the object out of a cacheable domain.

drm/i915: Specify bsd rings through exec flag

drm/i915: Consolidate forcewake code

As we now have forcewake domains, take advantage of it
by putting the differences in gen fw handling in data rather
than in code.

In past we have opencoded this quite extensively as the fw handling
is in the fast path. There has also been a lot of cargo-culted
copy'n'pasting from older gens to newer ones.

Now when the releasing of the forcewake is done by deferred timer,
it gives chance to consolidate more. Due to the frequency of actual hw
access being significantly less.

Take advantage of this and generalize the fw handling code
as much as possible. But we still aim to keep the forcewake sequence
particularities for each gen intact. So the access pattern
to fw engines should remain the same.

drm/i915: Configure GEN6_RP_DOWN_TIMEOUT on CHV

CherryViewA0_iGfx_BIOS_DRIVER_PUNIT_spec_y14w28d5 tells us not to enable
the RP down timeout interrupt, and says that the timeout value is hence
not used. We do enable that interrupt currently though, so leaving the
timeout as 0 results in very poor performance as the GPU frequency keeps
dropping constantly. So just program the register with the recommended
value.

Leaving the interrupt enabled doesn't seem to do any harm so far. So
I've decided to leave it on for now, just to avoid making CHV a
special case.

This fixes the performance regression from:

drm/i915: Don't cleanup plane state in intel_plane_destroy()

When we transitioned to the atomic plane helpers in commit:

        Date:   Tue Dec 23 10:41:52 2014 -0800

            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 3009c0377f25c29852b218a6933a969d02cbdc5d

            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.

drm/exynos: remove struct exynos_drm_overlay

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.
