When CONFIG_LOONGSON_LIOINTC,CONFIG_LOONGSON_EIOINTC,
CONFIG_LOONGSON_PCH_LPC,CONFIG_LOONGSON_PCH_PIC was disabled,
build kernel with errors like:

MODPOST vmlinux.symvers
MODINFO modules.builtin.modinfo
GEN     modules.builtin
LD      .tmp_vmlinux.kallsyms1
loongarch64-linux-gnu-ld: drivers/irqchip/irq-loongarch-cpu.o: in function `lpic_get_gsi_domain_id':
