Move the get/put/ref/flush_for_display calls to the display parent interface. For i915, move the hooks next to the other i915 core frontbuffer code in i915_gem_object_frontbuffer.c. For xe, add new file xe_frontbuffer.c for the same. Note: The intel_frontbuffer_flush() calls from i915_gem_object_frontbuffer.c will partially route back to i915 core via the parent interface. This is less than stellar.
