Make drm_mode_add_fb() call drm_mode_add_fb2() after converting its
args to the new internal format, instead of duplicating code.
Also picks up a lot more error checking, which the legacy modes
should pass after being converted to the new format.

This fixes a regression introduced by "drm/nouveau: rework to new fence interface"
(commit 29ba89b237).
The fence sequence should not be reset after creation, the old value is used instead.
On destruction the final value is written, to prevent another source of accidental
wraparound in case of a channel being destroyed after a hang, and unblocking any other
channel that may wait on the about-to-be-deleted channel to signal.
I'm nothing if not optimistic about any hope of recovery from that. ;-)

Paulo Zanoni reported a lockdep splat with a locking inversion between
fpriv->fbs_lock and the modeset locks. This issue was introduced in
commit f2b50c1161
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Fri Sep 12 17:07:32 2014 +0200
drm: Fixup locking for universal cursor planes
This here is actually one of the rare cases where lockdep hits a false
positive: The deadlock only happens in drm_fb_release, which cleans up
the file private structure when all the references are gone. So the
locking is the very last one and no one else can deadlock. It also
doesn't protect anything at all, since all ioctls are guaranteed to
have returned at this point - otherwise they'd still hold a reference
on the file.
So let's just drop it and replace it with a big comment.

Bunch of things amiss:
- Updating crtc->cursor_x/y was done without any locking. Spotted by
David Herrmann.
- Dereferencing crtc->cursor->fb was using the wrong lock, should take
the crtc lock.
- Grabbing _all_ modeset locks torpedoes the reason why we added
fine-grained locks originally: Cursor updates shouldn't stall on
background stuff like probing outputs.
Best is to just grab the crtc lock around everything and drop all the
other locking. The only issue is that we can't switch planes between
crtcs with that, so make sure that never happens when someone uses
universal plane helpers. This shouldn't be a possible regression ever
since legacy ioctls also only grabbed the crtc lock, so switching
crtcs was never possible for the underlying plane object. And i915
(the only user of universal cursors thus far) has fixed cursor->crtc
links.

If we already have a timestamp for the current vblank counter, don't
update it with a new timestmap. Small errors can creep in between two
timestamp queries for the same vblank count, which could be confusing to
userspace when it queries the timestamp for the same vblank sequence
number twice.
This problem gets exposed when the vblank disable timer is not used
(or is set to expire quickly) and thus we can get multiple vblank
disable<->enable transition during the same frame which would all
attempt to update the timestamp with the latest estimate.

Sorry for late. This pull request includes some enhancements
for Exynos drm, new feature supports, cleanups and fixups
like below,
- Consider low power transmission for drm mipi dsi module,
and also add non-continuous clock mode support for Exynos
mipi dsi driver.
- Add Exynos3250 SoC support.
- Enhance and clean up ipp framework and fimc driver.
- Update to use component match support and fix up
de-initialization order.
- Remove a direct mmap interface and relevant stuff specific to
Exynos drm, use drm generic mmap interface instead.
And we will remove the specific interface from userspace
library, libdrm soon.
- Use universal plane which allows to replace fake primary plane
with the real one.
- Some code cleanups and fixups.

This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific
to Exynos drm and instead uses drm generic mmap.
We had used the interface specific to Exynos drm to do mmap directly,
not to use demand paging which maps each page with physical memory
at page fault handler. We don't need the specific mmap interface
because the drm generic mmap which uses vm offset manager stuff can
also do mmap directly.
This patch makes a userspace region to be mapped with whole physical
memory region allocated by userspace request when mmap system call is
requested.
Changelog v2:
- do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already
set by drm_gem_mmap
- do not include <linux/anon_inodes.h>, which isn't needed anymore.
