drm/i915: Restore memory mapping for DPT FBs across system suspend/resume
...
At least during hibernation the DPT mappings are lost with all stolen
memory content, so suspend/resume these mappings similarly to GGTT
mappings.
This fixes a problem where the restoring modeset during system resume fails
with pipe faults if a tiled framebuffer was active before suspend.
v2: Clarify the way restore works in intel_dpt_resume()'s Docbook entry.

drm/i915: Add ww context to intel_dpt_pin, v2.
...
Ensure i915_vma_pin_iomap and vma_unpin are done with dpt->obj lock held.
I don't think there's much of a point in merging intel_dpt_pin() with
intel_pin_fb_obj_dpt(), they touch different objects.
Changes since v1:
- Fix using the wrong pointer to retrieve error code (Julia)

We don't care about __iomem mismatch when dealing with error
