[Intel-gfx] Updated -next

Hi Dave,

QA beat on the -next tree in my absence and filed 3 new issue. Afaict
they're all new sightings of old issues (hooray for improved test-suites)
safe for a very funky sporadic failure on ilk - investigation is still
going on this one.

Otherwise the missed irq on snb poped up again, but Ben confirmed that the
full ivb voodoo works. You likely get a one-liner to enable that on snb,
too. And imo the swizzling regression has been fixed as well as possible
given the ugly situation - the patch to fix lying kernels prior to 3.2 is
submitted to stable (needed for correctness with updated mesa git/8.0)
and the mesa patch to correctly detile the stencil buffer is on track to
get into the next 8.0 release (the only affected mesa release branch).

Highlights of this pull request:
- gmbus fixes and reenabling gmbus by default (one-liner to switch back).
  Note that this also contains a i2c core change and a i2c patch for
- random smaller fixes and some quirks
- the finish_gpu patch, despite the lack of a clear testcase and and
  obviously correct theory how exactly this fixes anything. But this does
  paper too well over various issues (among them the hibernate desaster,
  at least to some extent), so I've grumpily included it.
i.e. winding down for 3.4.

PSA to everyone else: I expect the next -next to go into 3.5 already, so
if I've picked up patches that you think should go into 3.4, please annoy
Keith about them.

As usual, qa report below the pull request.

Cheers, Daniel
