Subject: [RFC PATCH 3/3] drm: use new debugfs functions for various files.

Replace the use of drm_debugfs_create_files with the new
drm_debugfs_add_files() to create various drm core debugfs files.

DRM debugfs files are also represented using the new drm_simple_info
struct for use with the new functions.
