powerpc/psurge: Create a irq_host for secondary cpus
Create a dummy irq_host using the generic dummy irq chip for the secondary
cpus to use. Create a direct irq mapping for the ipi and register the
ipi action handler against it. If for some unlikely reason part of this
fails then don't detect the secondary cpus.
This removes another instance of NO_IRQ_IGNORE, records the ipi stats
for the secondary cpus, and runs the ipi on the interrupt stack.
