As suggested by Marc and Arnd, these two patches are the minimal changes
required on irqchip's side to make the LoongArch port build, without
introducing any non-reviewed pieces of code.

V1 -> V2:
Add a cover letter and fix commit message.

Huacai Chen:
 irqchip: Adjust Kconfig for Loongson.
 irqchip/loongson-liointc: Fix build error for LoongArch。
