[PATCH -next] irqchip: mips-gic: Make some symbols static

[Wei Yongjun <weiyongjun1@huawei.com>]

The sparse tool complains as follows:

drivers/irqchip/irq-mips-gic.c:49:1: warning:
 symbol '__pcpu_scope_pcpu_masks' was not declared. Should it be static?
drivers/irqchip/irq-mips-gic.c:620:6: warning:
 symbol 'gic_ipi_domain_free' was not declared. Should it be static?
drivers/irqchip/irq-mips-gic.c:634:5: warning:
 symbol 'gic_ipi_domain_match' was not declared. Should it be static?

Those symbols are not used outside of irq-mips-gic.c, so marks
them static.
