drm/{i915, xe}/display: Add display runtime pm parent interface

Browse Source 
We have differing implementations for display runtime pm in i915 and xe
drivers. Add struct of function pointers into display_parent_interface
which will contain used implementation of runtime pm.

v2:
  - add _interface suffix to rpm function pointer struct
  - add struct ref_tracker forward declaration
  - use kernel-doc comments
