My smp code is exactly the same as mach-virt with this, but adds cpu_die
for hotplug. smp_secondary_init will go away with Catalin's series to
use notifiers for the gic secondary init. This leaves smp_boot_secondary.

We could move these remaining smp_ops to psci.c and create psci_smp_ops.
That probably needs to be after the gic notifier changes.

Your patch, psci smp ops, and converting the arch timers to use
OF_CLKSRC_DECLARE will eliminate mach-virt unless Will has more things
planned for it.
