[PATCH v11 3/7] LoongArch: Move irqchip function prototypes to irq-loongson.h

[Tianyang Zhang]

From: Huacai Chen <chenhuacai@xxxxxxxxxxx>

Some irqchip functions are only for internal use by irqchip drivers, so
move their prototypes from asm/irq.h to drivers/irqchip/irq-loongson.h.

All related driver files include the new irq-loongson.h.
