[PATCH v3 6/7] drm/i915/de: allow intel_display and drm_i915_private for de functions

[Jani Nikula]

It would be too much noise to convert the intel_de_* functions from
using struct drm_i915_private to struct intel_display all at once. Add
generic wrappers using __to_intel_display() to accept both.

This was done using a cocci + shell script combo.
