arcbios: add hazard nops for pre-R4000 MIPS1 machines

All MIPS ARC (Advanced RISC Computing) machines have R4000/R4400

 https://www.netbsd.org/docs/Hardware/Machines/ARC/

as supported by NetBSD/arc and they don't require nops,
but the sgimips port fakes ARCS for older R2k/R3k machines,
so it uses this code on older CPUs, too.
