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.
