This removes the nastiness with the interactions between display and
software engines when handling vblank semaphore release interrupts.
Now, all the semantics are handled in one place (sw) \o/.

This is a precursor to dynamic power management support for nouveau,
we need to use pm ops for that, so first convert the driver to using pm ops
interfaces.

Pull drm merge (part 1) from Dave Airlie:
"So first of all my tree and uapi stuff has a conflict mess, its my
fault as the nouveau stuff didn't hit -next as were trying to rebase
regressions out of it before we merged.
Highlights:
- SH mobile modesetting driver and associated helpers
- some DRM core documentation
- i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
combined pte writing, ilk rc6 support,
- nouveau: major driver rework into a hw core driver, makes features
like SLI a lot saner to implement,
- psb: add eDP/DP support for Cedarview
- radeon: 2 layer page tables, async VM pte updates, better PLL
selection for > 2 screens, better ACPI interactions
The rest is general grab bag of fixes.
So why part 1? well I have the exynos pull req which came in a bit
late but was waiting for me to do something they shouldn't have and it
looks fairly safe, and David Howells has some more header cleanups
he'd like me to pull, that seem like a good idea, but I'd like to get
this merge out of the way so -next dosen't get blocked."
Tons of conflicts mostly due to silly include line changes, but mostly
mindless. A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

Kepler PFIFO lost the ability to address multiple engines from a single
channel, so we need a separate one for the copy engine.

This is a HUGE commit, but it's not nearly as bad as it looks - any problems
can be isolated to a particular chipset and engine combination. It was
simply too difficult to port each one at a time, the compat layers are
*already* ridiculous.
Most of the changes here are simply to the glue, the process for each of the
engine modules was to start with a standard skeleton and copy+paste the old
code into the appropriate places, fixing up variable names etc as needed.

These currently just call the existing ones in nouveau_drv.c, but will be
extended in upcoming commits. This needed to be separated from the current
code as there will be some header clashes until things are ported.
