[PATCH] irqchip: loongarch-cpu: Fix a missing prototype warning

[Huacai Chen]

1, Rename loongarch_cpu_irq_of_init() to cpuintc_of_init() in order to
   keep the same style as the ACPI version.
2, Fix a missing prototype warning by adding a "static" modifier.

Fixes: 855d4ca4bdb366aab3d4 ("irqchip: loongarch-cpu: add DT support")
