drm/i915/debugfs: remove i915_display_capabilities

Turns out we've added two similar debugfs files. Consolidate on
intel_display_caps as it has more info and a driver independent name.

IGT has already switched over to intel_display_caps in IGT commit
cf837fc17d6c ("lib/dsc: use intel_display_caps instead of
i915_display_capabilities").
