[PATCH v2 1/7] drm/etnaviv: use new debugfs device-centered functions

[Maíra Canal <mcanal@xxxxxxxxxx>]

Replace the use of drm_debugfs_create_files() with the new
drm_debugfs_add_files() 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 etnaviv_bind(),
before drm_dev_register().
