drm/i915/display: Use display parent interface for i915 runtime pm

Start using display parent interface for i915 runtime pm. Doing the same
for xe is done in coming changes.

v3:
  - remove useless include
v2:
  - use <> when including drm/intel/display_parent_interface.h
  - drop checks for validity of rpm function pointers
