irqchip/loongson-pch-pic: Fix registration of syscore_ops 



When support suspend/resume for loongson-pch-pic, the syscore_ops
is registered twice in dual-bridges machines where there are two
pch-pic IRQ domains. Repeated registration of an same syscore_ops
broke syscore_ops_list, so the patch will corret it.
