ARM: gic: add OF based initialization
This adds ARM gic interrupt controller initialization using device tree
data.
The initialization function is intended to be called by of_irq_init
function like this:
const static struct of_device_id irq_match[] = {
{ .compatible = "arm,cortex-a9-gic", .data = gic_of_init, },
{}
};
static void __init init_irqs(void)
{
of_irq_init(irq_match);
}
