informs us what gets pinned into which address space.

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

Here created intel_dpt_common.c to hold intel_dpt_configure which is
needed for both xe and i915.

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.

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.

Let's try to reduce the size of intel_display.c, not increase it.
