5c0422878f drm/i915: ILK + VT-d workaround
Idle the GPU before doing any unmaps. We know if VT-d is in use through
an exported variable from iommu code.

This should avoid a known HW issue.

1996675432 drm/i915: die, i915_probe_agp, die
Use the detection from intel-gtt.ko instead. Hooray!

Also move the stolen mem allocator to the other gtt stuff in dev_prv->mem.

v2: Chris Wilson noted that my error handling was crap. Fix it. He also
said that this fixes a problem on his i845. Indeed, i915_probe_agp
misses a special case for i830/i845 stolen mem detection.

0ade638655 intel-gtt: introduce drm/intel-gtt.h
Add a few definitions to it that are already shared and that will
be shared in the future (like the number of stolen entries).
No functional changes in here.
