Unifying the various seq_puts messages in debugfs to the simplest one for
feature support.
v2: Clarifying the commit message (Anusha)
v3: Re-factoring code as per review (Michal)
v4: Rebase
v5: Split from following patch
v6: Re-factoring code (Michal, Sagar)
Clarifying commit message (Sagar)
v7: Generalizing subject to drm/i915 (Sagar)
v8: Omitting DRRS seq_puts unification (Michal)
v9: Including the HAS_HUC condition (Michal)
Updating more functions with unified message (Sagar)
