[PATCH v2 3/7] drm/arc: use new debugfs device-centered functions

[Maíra Canal]

Replace the use of drm_debugfs_create_files() with the new
drm_debugfs_add_file() function, which centers the debugfs files
management on the drm_device instead of drm_minor. Moreover, remove the
debugfs_init hook and add the debugfs files directly on arcpgu_probe(),
before drm_dev_register().
