cmd: ubi: delete useless and misleading definitions

These definitions are simply not used and are misleading because similar
definitions exist in jffs2/load_kernel.h and are used widely to define
MTD device types (which is, by the way, totally redundant with what the
MTD core does). Remove these definitions.
