hw/arm/virt: Wire up secure timer interrupt
Wire up the secure timer interrupt. Since we've defined
that the plain old physical timer is the NS timer, we can
drop the now-out-of-date comment about QEMU not having TZ.
Use a data-driven loop to wire up the timer interrupts, since
we now have four of them and the code is the same for each.
