MIPS: Provide empty mips_mt_set_cpuoptions when CONFIG_MIPS_MT=n
Both the CONFIG_MIPS_CPS & CONFIG_MIPS_CMP SMP implementations call mips_mt_set_cpuoptions when preparing to start secondary CPUs. However both may be used without MT. Provide an empty inline function to prevent a link error in this case.
