drm/i915/selftests: Add live vma selftest
Add a live selftest to excercise rotated/remapped vmas. We simply
write through the rotated/remapped vma, and confirm that the data
appears in the right page when read through the normal vma.
Not sure what the fallout of making all rotated/remapped vmas
mappable/fenceable would be, hence I just hacked it in the test.
v2: Grab rpm reference (Chris)
GEM_BUG_ON(view.type not as expected) (Chris)
Allow CAN_FENCE for rotated/remapped vmas (Chris)
Update intel_plane_uses_fence() to ask for a fence
only for normal vmas on gen4+
v3: Deal with intel_wakeref_t
v4: Rebase
