drm/i915: add generic __to_intel_display()
Add generic __to_intel_display() macro that accepts either struct
drm_i915_private * or struct intel_display *. This is to be used for
transitional stuff that eventually needs to be converted to use struct
intel_display *, and therefore is not part of to_intel_display().
Add new intel_display_conversion.h to host the helper to avoid
duplication between xe and i915 drivers.
v2: put it in the new header (Rodrigo)
