drm/i915: handle shared framebuffers when flipping
If a framebuffer is shared across CRTCs, the x,y position of one of them
is likely to be something other than the origin (e.g. for extended
desktop configs). So calculate the offset at flip time so such
configurations can work.

I have confirmed that a 2.6.35 with that one commit reverted works on my failing case. Once again, I have non-overlapping CRTCs of 1920x1080+0+0 and 1650x1050+1920+0. Hopefully Jesse and Eric will be able to get both my case and the reported bug working at the same time.
