Add a __drm_to_display() conversion function to hide the to_i915() usage and the implicit dependency on i915_drv.h from intel_display_types.h. The goal is for this implementation to be a transitional helper only. One idea I've floated around in the past would be to require a struct intel_display pointer member to be placed right after struct drm_device member in struct drm_i915_private and struct xe_device [1][2].
