commit cb6458f97b53d7f73043206c18014b3ca63ac345

drm: remove procfs code, take 2
Having the code shared between procfs and debugfs in the separate
drm_info.c file stopped making sense. Merge them.
Noticed because Lyude asked some questions on irc about why we even
have drm_info_node and I remember this old story.
