mtd: ubi: make ubi_class constant
Since commit 43a7206b0963 ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the ubi_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.
