Chagelog v2:
Move encoder's dpms updating into exynos_drm_encoder_commit
function because when crtc's dpms is updated, encoder's dpms
is updated also. This would induce the issue that encoder
isn't disabled after crtc is disabled.

Changelog v1:
This patch fixes a issue that overlay data aren't applied
to real hardware when dpms off goes to on after setcrtc
was requested like below,
    dpms off -> setcrtc -> dpms off -> dpms on

For this, it makes encoder's dpms to be updated when
setcrtc is requested.

Besides the big item of lifting the "preliminary hw support" tag from the
 Haswell code, just small bits&pieces all over:
 - Leftover Haswell patches and some fixes from Paulo
 - LyncPoint PCH support (for hsw)
 - OOM handling improvements from Chris Wilson
 - connector property and send_vblank_event refactorings from Rob Clark
 - random pile of small fixes

 Note that the send_vblank refactorings will cause some locking WARNs to
 show up. Imre has fixed that up, but since all the driver changes outside
 of the drm core have been for exonys, those four patches are merged
 through the exonys-next tree.

Meh, I've forgotten to cherry-pick an important fix from Ben for a
regression in the 3.8 gen6+ gtt code. New pull request below. While I'm at
it, the hdmi VIC patch for the drm edid code is still in my queue, I'll
send you that in the next 3.8-fixes pull.

This bug was introduced by me:
commit e76e9aeb
Author: Ben Widawsky <ben@bwidawsk.net>
Date:   Sun Nov 4 09:21:27 2012 -0800

    drm/i915: Stop using AGP layer for GEN6+

The existing code uses memset_io which follows memset semantics in only
guaranteeing a write of individual bytes. Since a PTE entry is 4 bytes,
this can only be correct if the scratch page address is 0.

This caused unsightly errors when we clear the range at load time,
though I'm not really sure what the heck is referencing that memory
anyway. I caught this is because I believe we have some other bug where
the display is doing reads of memory we feel should be cleared (or we
are relying on scratch pages to be a specific value).

Previously, if either vram/gart handles were specified as ~0, the ioctl
call would fail.  In order to hack engine selection into the ioctl for
kepler, we now define (fb_ctxdma_handle == ~0) to mean "engine mask is
in tt_ctxdma_handle".

This approach also allows new userspace to detect lack of support for
non-PGRAPH channels on older kernels.
