[PATCH_V2 06/34] MIPS: jz4740: move arch_init_irq out of arch/mips/jz4740/irq.c

[Zubair Lutfullah Kakakhel]

From: Paul Burton <paul.burton@xxxxxxxxxx>

In preparation for moving the jz4740 interrupt controller driver to
drivers/irqchip, move arch_init_irq into setup.c such that everything
remaining in irq.c is related to said jz4740 interrupt controller.
