[PATCH] MIPS: Loongson64: Make some functions static in irq.c

[zhaoxiao]

Make some functions static to fix the following sparse warnings:
arch/mips/loongson64/loongson-3/irq.c:15:14: warning: symbol 'irq_cpu' was not declared. Should it be static?
arch/mips/loongson64/loongson-3/irq.c:16:14: warning: symbol 'ht_irq' was not declared. Should it be static?
arch/mips/loongson64/loongson-3/irq.c:17:14: warning: symbol 'local_irq' was not declared. Should it be static?
arch/mips/loongson64/loongson-3/irq.c:19:5: warning: symbol 'plat_set_irq_affinity' was not declared. Should it be static?
arch/mips/loongson64/loongson-3/irq.c:112:6: warning: symbol 'irq_router_init' was not declared. Should it be static?
