We've used a temporary platform device for firmware EDID loading since
it was introduced in commit da0df92b5731 ("drm: allow loading an EDID as
firmware to override broken monitor"), but there's no explanation why.
Do we need to?
Maybe this fixes the suspend/resume issue?
(Yes, I'll rewrite the commit message if this is the way to go ;)
