[PATCH] drm/edid/firmware: stop using throwaway platform device

[Jani Nikula]

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 ;)
