Subject: [PATCH 1/2] irqchip: sunxi-nmi: Use driver name instead of DT node name for identification

The device tree node name is typically "interrupt-controller", which is
rather useless when used in printk messages and irq chip names for
identification purposes. Use the driver name "sunxi-nmi" instead.
