drm/i915/display: use drm->debugfs_root for creating debugfs files

Browse Source 
Since commit 0b30d57aca ("drm/debugfs: rework debugfs directory
creation v5") we should be using drm->debugfs_root instead of
minor->debugfs_root for creating debugfs files.

As a rule of thumb, use a local variable when there are two or more
uses, otherwise just have the single reference inline.

Drop drm/drm_file.h include where possible.
