drm/tilcdc: Remove tilcdc_debugfs_cleanup()

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so the drm_driver.debugfs_cleanup callback is not
needed. Also remove the unused tilcdc_module_ops.debugfs_cleanup()
callback. drm_debugfs_cleanup() removes all debugfs files using
debugfs_remove_recursive(), so there should be no need for such a
callback in the future.
