However, this is not necessary.  If you look at arch/arm/kernel/setup.c,
it contains this:

        psci_init();
#ifdef CONFIG_SMP
        if (is_smp()) {
                if (!mdesc->smp_init || !mdesc->smp_init()) {
                        if (psci_smp_available())
                                smp_set_ops(&psci_smp_ops);
                        else if (mdesc->smp)
                                smp_set_ops(mdesc->smp);
                }
                smp_init_cpus();
                smp_build_mpidr_hash();
        }
#endif

So, the platforms' SMP ops won't be used even if they're provided
when PSCI is available.
