drm/exynos: Properly report supported formats for each device
Exynos DRM reported that all planes for all supported sub-devices supports
only three pixel formats: XRGB24, ARGB24 and NV12. This patch lets each
Exynos DRM sub-drivers to provide the list of supported pixel formats
and registers this list to DRM core.

drm/exynos: implement atomic_{begin/flush} of DECON
Each CRTC's atomic_{begin/flush} must stop/start the update of shadow
registers to active register in the functions. This patch achieves these
purpose by moving the setting of protection bits to those functions from
decon_update_plane.

Exynos atomic commit procedures already does this job of waiting for

It also serializes commits that needs to run on the same crtc, putting the
following commit to wait until the current one is finished.

drm/exynos: fimd: only finish update if START == START_S
fimd_update_plane() programs BUF_START[win] and during the update
BUF_START[win] is copied to BUF_START_S[win] (its shadow register)

The fimd_irq_handler, in the case we have a pending_fb, will check
the fb value was copied to START_S register and finish the update
in case of success.

drm/exynos: check for pending fb before finish update
The current code was ignoring the end of update for all overlay planes,
caring only for the primary plane update in case of pageflip.
This change adds a change to start to check for pending updates for all
planes through exynos_plane->pending_fb. At the start of plane update the
pending_fb is set with the fb to be shown on the screen. Then only when to
fb is already presented in the screen we set pending_fb to NULL to
signal that the update was finished.

Merge branch 'linux-4.3' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
Rather large pull request this time around, due to the long-pending
cleanup of the kernel driver being here. There's a stupidly large
number of commits for that, as I wanted to have the series be
bisectable at a fairly fine-grained level. That said, a very large
portion of the churn in the rework was automated, and a very large
number of boards from right across the whole range we support have
been tested. I'm fairly confident there shouldn't be (too many)
issues from this.
Beyond correcting some not-so-great design decisions and making the
code a lot easier to work with, there's not much exciting (lower
memory usage, GPU VM should be a lot faster, etc) to be gained by the
end-user as a result of the cleanup, it mostly lays the groundwork for
future improvements.
A big thanks goes to Alexandre Courbot for testing/debugging the GK20A
codepaths for me :)
Highlights:
- A heap of perfmon work, providing a more useful userspace interface
and specifying counters for a bunch of boards
- Support for GT200 reclocking + other misc pm improvements
- Initial patches towards supporting GM20B (Tegra X1)
- Maxwell DisplayPort fixes
- Cleanup of the kernel driver
- The usual collection of random fixes
