The structs drm_debugfs_info and drm_debugfs_entry don't have
descriptions for their parameters, which is causing the following warnings:

'name' not described in 'drm_debugfs_info'
include/drm/drm_debugfs.h:93: warning: Function parameter or member

'file' not described in 'drm_debugfs_entry'
include/drm/drm_debugfs.h:105: warning: Function parameter or member
'list' not described in 'drm_debugfs_entry'

Therefore, fix the warnings by adding descriptions to all struct
parameters.
