mips: mt: make mt_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 mt_class structure to be declared at build time placing
it into read-only memory, instead of having to be dynamically allocated at
boot time.
