[PATCH v2 2/7] drm/pl111: use new debugfs device-centered functions

[Maíra Canal <mcanal@xxxxxxxxxx>]

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 pl111_amba_probe(),
before drm_dev_register().
