drm/sti: Remove drm_debugfs_remove_files() calls

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so it's not necessary to call
drm_debugfs_remove_files(). Additionally it uses
debugfs_remove_recursive() to clean up the debugfs files, so no need
for adding fake drm_info_node entries.
