MIPS: MT: Remove SMTC support Nobody is maintaining SMTC anymore and there also seems to be no userbase. Which is a pity - the SMTC technology primarily developed by Kevin D. Kissell <kevink@paralogos.com> is an ingenious demonstration for the MT ASE's power and elegance. Based on Markos Chandras <Markos.Chandras@imgtec.com> patch https://patchwork.linux-mips.org/patch/6719/ which while very similar did no longer apply cleanly when I tried to merge it plus some additional post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to merge once upon a time.

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.
