drm/i915: Use intel_display wherever possible

Use struct intel_display wherever possible in intel_display_debug_fs.c
to reduce the use of drm_i915_private.
While at it do the opportunistic display->platform.xx replacement.

--v2
-Rebase

--v3
-Don't use inline to_intel_display [Jani]
-Don't use display debug fs as subject prefix [Jani]
