irqchip/sun4i: Fix compilation outside of arch/arm

The Allwinner sunxi specific interrupt controller cannot be compiled
for any architecture except arm:

drivers/irqchip/irq-sun4i.c:25:26: fatal error: asm/mach/irq.h: No such file or directory
compilation terminated.

It turns out that this header is actually not needed for the driver, so remove
it and allow compilation for other architectures like arm64.
