Subject[PATCH 1/2] irqchip: Fixed LoongArch CPU interrupt types defined.
Date
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':
irq-loongarch-cpu.c:(.text+0x8): undefined reference to `pch_lpc_handle'
loongarch64-linux-gnu-ld: irq-loongarch-cpu.c:(.text+0xc): undefined reference to `pch_lpc_handle'
loongarch64-linux-gnu-ld: irq-loongarch-cpu.c:(.text+0xc): undefined reference to `pch_lpc_handle'
make: *** [Makefile:1171:vmlinux] 错误 1
