irqchip: gic: Perform the gic_secondary_init() call via CPU notifier

Browse Source 
All the calls to gic_secondary_init() pass 0 as the first argument.
Since this function is called on each CPU when starting, it can be done
in a platform-independent way via a CPU notifier registered by the GIC
code.
