Convert drivers/gpu/drm class to use dev_pm_ops for power management and
remove Legacy PM ops hooks. With this change, drm class registers
suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy
class->suspend/resume. When __device_suspend() runs call-backs, it will
find class->pm ops for the drm class.

drm_class_suspend() hook calls driver legacy ops with the state information.
e.g: drm_class_suspend() calls into driver suspend routines
via drm_dev->driver->suspend(drm_dev, state).

Once drm_class_suspend() is converted to dev_pm_ops, it will no longer
have access to pm_transition which it has to pass into driver legacy
suspend calls. A new freeze and suspend hooks are added to address the not
having access to the state information. The new freeze and suspend hooks
simply call __drm_class_suspend() with the appropriate pm state information.
__drm_class_suspend() is the original suspend hook with a new name.

Merge tag 'drm-intel-fixes-2013-07-03' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Pile of fixes for 3.11. A bit large in patch count, but that's simply due
to two fixes being split up into really small parts. Also I've included a
few more vlv patches than I'd have included for other platforms. But since
vlv is officially supported for the first time only in 3.11 that shouldn't
result in unbearable risks.

Highlights:
- ghost eDP fixes for hsw from Paulo
- fix PCH detection in virtualized enviroments (Rui Guo)
- duct-tape dma sg construction when swiotlb is in use (Konrad), dupe with
  a patch in your drm-fixes branch
- fix sdvo hotplug on i965g
- tune down a bunch of dmesg ERRORs which can be hit under normal
  conditions
- detect invalid pitches for tiled scanout buffers (Chris)
- a pile of vlv fixes from Ville: rps improvements, fixes for the dpll
  LPF, fixup the sprite mmio offsets
- fix context size on hsw (Ben)
- locking fixes for the hotplug code, specifically the storm handling
- fix get_config on CPT (Xiong Zhang)
- Fix the domain tracking when an unlocked seqno wait was interrupt
  (Chris), this seems to explain tons of little corruption bugs in the
  ddx. Chris also added a nice igt to exercise this.
- work around stack-corrupting vnsprintf in our error state dumper

Every other place properly checks whether we've managed to set
up the stolen allocator at boot-up properly, with the exception
of the cleanup code. Which results in an ugly

*ERROR* Memory manager not clean. Delaying takedown

at module unload time since the drm_mm isn't initialized at all.

v2: While at it check whether the stolen drm_mm is initialized instead
of the more obscure stolen_base == 0 check.

v3: Fix up the logic. Also we need to keep the stolen_base check in
i915_gem_object_create_stolen_for_preallocated since that can be
called before stolen memory is fully set up. Spotted by Chris Wilson.

v4: Readd the conversion in i915_gem_object_create_stolen_for_preallocated,
the check is for the dev_priv->mm.gtt_space drm_mm, the stolen
allocatot must already be initialized when calling that function (if
we indeed have stolen memory).

So it appears that I have encountered some bogosity when trying to call
i915_error_printf() with many arguments from print_error_buffers(). The
symptom is that the vsnprintf parser tries to interpret an integer arg
as a character string, the resulting OOPS indicating stack corruption.
Replacing the single call with its 13 format specifiers and arguments
with multiple calls to i915_error_printf() worked fine. This patch goes
one step further and introduced i915_error_puts() to pass the strings
simply.

It may not fix the root cause, but it does prevent my box from dying and
I think helps make print_error_buffers() more friendly.

Harmonise the completion logic between the non-blocking and normal
wait_rendering paths, and move that logic into a common function.

In the process, we note that the last_write_seqno is by definition the
earlier of the two read/write seqnos and so all successful waits will
have passed the last_write_seqno. Therefore we can unconditionally clear
the write seqno and its domains in the completion logic.

v2: Add the missing ring parameter, because sometimes it is good to have
things compile.

In the introduction of the non-blocking wait, I cut'n'pasted the wait
completion code from normal locked path. Unfortunately, this neglected
that the normal path returned early if the wait returned early. The
result is that read-only waits may return whilst the GPU is still
writing to the bo.
