irqchip/gic: Convert to hotplug state machine
More or less straightforward, although this driver sports some very
interesting SMP setup code. Regarding the callback ordering, this
deleted comment is interesting:
... the GIC needs to be up before the ARM generic timers.
That comment is half baken as the same requirement is true for perf.
