d1bba730a1 drm/i915/dpt: convert intel_dpt.[ch] interfaces to struct intel_display 
Going forward, struct intel_display is the main display device data
pointer. Convert the intel_dpt.[ch] interfaces to struct intel_display,
though the file being very i915 specific, it's hard to convert the
implementation.

6dbd43dced drm/{i915, xe}: Avoid direct inspection of dpt_vma from outside dpt 
DPT code is so dependent on i915 vma implementation and it is not
ported yet to Xe.

This patch limits inspection to DPT's VMA struct to intel_dpt
component only, so the Xe GGTT code can evolve.

c8bafa0d98 drm/i915: Align PLANE_SURF to 16k on ADL for async flips 
On ADL async flips apparently generate DMAR and GGTT faults
(with accompanying visual glitches) unless PLANE_SURF is
aligned to at least 16k. Bump up the alignment to 16k.

TODO: analyze things better to figure out what is really
      going on here

c5de248484 drm/i915/dpt: Add a modparam to disable DPT via the chicken bit 
Add i915.enable_dpt modparam to allow disabling the DPT
usage in hardware via the chicken bit. Useful when debugging
potential DPT issues.

Quickly smoke tested on ADL.

9755f055f5 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.
