Pseudo registers (like CP15_UNIMPL) have been moved after the NUM_PHYS_MISCREGS identifier, so that their enum number is (NUM_PHYS_MISCREGS < number < NUM_MISCREGS). Moving away those registers has created some free slots that can be used for future Misc register implementation. SERIALIZE and UNSERIALIZE now only save/restore PHYSICAL Misc Registers. This allows us to define as many pseudo registers as we want without being concerned about checkpoint compatibility.
