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.

While at it move the identifier from pr_err() calls to the pr_fmt macro.

Also remove the "__func__" identifier from the error message in the
interrupt type setting callback, sunxi_sc_nmi_set_type(). The driver
name in the pr_fmt macro should be enough.
