IRQCHIP: irq_cpu: declare irqchip table entry

Allow the MIPS CPU interrupt controller to be probed from DT using the
generic __irqchip_of_table for platforms which use irqchip_init. This
will avoid such platforms needing to duplicate the compatible string &
init function pointer.

[ralf@linux-mips.org: Resolved conflict due the preceeding commit that
moves irq-cpu.c.
